Our game is all about evolving the FPS recipe with all the inspirations we've assimilated since the birth of the genre. Our goal is an evolutionary leap forward driven by our compulsive interest in science fiction, role-playing, military realism, and respect for first person immersion.

Early Access Review
uh, so let me tell you a story.

in 2009 This dev, collects alot of money to make you a game. This game dev, for whatever reason, blows every cent they got from funding on whatever they wanted. Silly right? hah. hah. well, they did it. Not only did they do that, but then they had the balls to try and put the game up AGAIN, except this time, they expect you to pay money for it. Not bad, right? supporting the dev to get the game. well, heh, get this. All premium accounts that were promised a version of the game were somehow "lost" or something, because I was one of those fools in 2011 that bought the premium account, and I have had no word on when I get my free key. Oh, don't worry. This is just the beggining.

After that, they started a crowdfunding for this game. Got a ♥♥♥♥ ton of money, for a game they already has essentially done. They said something about engine rights. So, here they go again, they got a literal ♥♥♥♥ ton of money and more than enough to buy the engine rights 100 times. So you might be thinking, here comes the release?

Well.. too.♥♥♥♥ing.bad.

They realease on steam in late 2012/early 2013. Oh, and guess what? It's in early access. AGAIN. I'm guessing to create an illusion saying they're working on the game and they need your support to help finish it. Right?

Wrong. Again.

It's may, 2015. This game has been in early access for YEARS. Just on steam! Oh, wait, it's not over.

Want to know how they got away with it? Because they can. And because illerate ♥♥♥♥tards on reddit and steam mindlessly defended this game, saying "oh just give them time!" Well guess ♥♥♥♥ing what? I've gave them 6 ♥♥♥♥ing years to get their ♥♥♥♥ together, and I don't see any game even a quarter of the way done. Really? I'll list some sources below, if you're interested. Once you get on this page, scroll to the VERY bottom. The first post is from the 15th of may 2009, with media showing the game already at least being worked on for a while.

Oh, here's a screencap incase anyone's lazy or incase they bring the link down.

♥♥♥♥ you, Zero Point Software.

Early Access Review
Hey guys,
Firstly this game really does amaze me; so much so that I have spent over 212hrs of my life on it!
Here is a little overview of the entire game as well as answers to myths circulating

There are currently two types of enemy androids or CTR's these being
-Continuously moving Sentry with an assault rifle
-A fast moving Android that melee attacks with his arms
(Landsharks soon, HOPEFULLY!)
In the multiplayer maps the enemies are only players

There are currently two weapons with 3 fire modes and 2 attachments these are the Assault Rifle (AR)
and the SMG each configurable with the fire rates of Automatic, Burst and Single Shot and the attachments of a flashlight and laser! (I dont recommend the lasers in combat as it gives away your position)

Interstellar Marines currently holds 4 Multiplayer Gamemodes
-Team Deathmatch
-Team Domination

They are accompanied with their 9 different SinglePlayer and 4 player Co-op counterparts
-Welcome to project IM (Singleplayer only)
-Assault on Starcrown Aerospace
-The Neurogen Incident
-Get Killed by bots (Singleplayer Only)
-Elimination A Stronghold
-Elimination B Mainline
-Survival A Operations
-Survival B Colony
-Escape A Nucleus

There are currently 9 multiplayer maps
-Evacuation - Large wasteland map
-Mainline- Spread out map with 4 main buildings and one open middle zone
-Mainline Winter - Winter version of Mainline
-Operations - Tight and maze like map
-Rupture - Large map that consists of two ends each with a building.
Each consists of several immersive variable environments such as Dawn, Foggy/Overcast, Rain, Day, Night and Fire Alarm.

Ranking System
The ranking system uses Training Points (TP) earned by completion of Gamemodes or kills to give you a Training Rank (TR). As your Training Rank increases so does the TP required to earn the next training rank. It is currently 5TP per kill. I am at TR-91 (Goes to TR-100) and it is costing me 10000TP to rank up 1 TR (2000 kills!!!)

1. "The devs have abandoned the game" , This is COMPLETELY FALSE! They are still here and working as hard as ever.
2. "Where are the Landsharks?", The land-sharks will come, EVENTUALLY! They are not here yet!

This game is my favourite, I play it everyday and I hope you share my love for it; if you decide to buy it. I hope I have answered some burning questions that you had, It is continually being updated and the Developers are really really nice to talk to as well as active and reading the forums continuously! I really hope you enjoy it as much as I do.

By the way, I own the Spearhead Edition 'DEM SOUNDTRACKS!'

Thanks for your time
-O.N.- ConjuredMadness :-)

PS. Feel free to add me to play IM with me or ask me questions about the game!

Early Access Review
This game is missing too much and the gameplay itself is not enjoyable enough to make up for the lack of content. Six years is a long time to be working on a game and I expect there to be more available after all that time. I will say I do like the coop missions. They have a suspenseful atmosphere. Like I have been saying though, I just wish there was more content than just the same two enemies, same two guns, and same objectives. Definitely not worth the $19. I would recommend it if the price was below $10.

Early Access Review
I played Slender without jumping. I played Amesia without flinching. I sat through Five Nights at Freddies and only jumped once.

But this game regularly makes me actually scream, and flinch badly enough I can't aim properly. I can't place exactly what does it, or why it does it so well, but holy ♥♥♥♥ does it ever. The noises the bots make, the way they lunge for you, the absolutely jawdropping immersion. This game isn't billed as a horror, and in reality, it shouldn't be. You play a fully armored, trained Marine, with unlimited ammo, flashlights, lasers, and the most advanced weapons in the entire armed forces. It couldn't be a survival horror, or even really a horror at this rate.

What it is is a very tense, tight, amazing shooter. Controls are absolutely tight (With the exception of stairwalking) weapons feel good, the lighting is top notch, and the sound is literally eargasmic. Everything combines to make a game that takes a badass fighter, and makes them seem like a very human fighter. The Marines say nothing, but you feel like you're actually there, fighting in their boots, sweating around the grips of their weapons. It's barely alpha even now, with many features missing and planned, and many bugs and issues.

And yet, it's still the best first person shooter I've played. It may not be the funnest, nor the fastest, nor even the most well polished. But it's a true first person experience, injecting you into the game in a way that I've wished for in many others.

Early Access Review
This is an user friendly game review/in game useer manual for Interstellar marines xDDDDD

Interstellar Marines, is an first person shooter game (FPS)
It is yet only in the early-access stage wich means that this game may, or may not be finished. But as it seems like right now the devs will continue this game. The first impression of this game when i first saw the video that plays when you first start up the game was great. the game has great overall graphics and suits pretty much all computers (within limitations) you do not need to have an super computer to play this game and it gives good fps.
In the begining you will start straight on the training course to get used to the controls.
then you are on your'e own. you can choose to play either single player (story mode/campaign) or you can jump over to co-op or versus mode. but first off im gonna talk about single player:

Single player means that you play versus the computer, (also called bots/Ai's)
The bots in this game are well made, they seem to be "artificial intelligent" they detect you easier when you stand/run than they do when you crouch and move slowly.
In game you will also have the options to equip lights (F), laser aim on your gun (G) or supressor (Q) when you use laser and the flashlight in game be carefull,\ because other players in game can see the laser and the flashlight (bots too)
they detect you a lot more faster when you have laser and flashlight enabled.
If you do not use the sound supressor on your gun, then be adviced. within a few seconds you will hear tons of robots stomping in the ground and coming sprinting towards you and ready to bash your skull in with their fists :)

the envoirment in the game is mostly dark/foggy so it is hard to spot enemies as well as it is hard to stay hidden if you will have to use your flashlight. this is why i often like strobing the flashlight for few moments as it can be mistaken to be lights in game that flimmers.

The thing with this game is that there are not very many guns. wich makes this game more focused on how actually skilled you are isntead of all the gear.
some peopels like it. some peoples dont.

the physics in the game are great. movement are well balanced as well as the gravity, in this game you do not have a bar that shows your stamina. but you still have it. so dont be sprinting around like a maniac. because this will affect how well you can aim when youre standing still as you will soon start to breathe like you have held your breath for 5 mina haha.

in game you can comunicate with different players. both with text and with voice chat. voice (V) chat is more prefered as the text does not show up before you open the "text menu" where you writes your messages, so they do not pop up on your screen automatically.

If you like to change graphics settings or general game settings and key bindings, then there is an fair ammount of options to use. and the game has a good compability to most screens. wich is quite good as i am using an 50" tv while i play. wich can be troubling in many games.

Also, every single bullet you fire in this game counts. the STATS menu will show you absolutely everything, and by saying this i mean absolutely EVERYTHING
you can see how many bullets you have shot, how many kills, how many deaths, kill/death ratio, wich body part you have hit the most. and how many times you have hit the different body parts counted per bullet.

so theres lot of room for competition with your friends about the best stats.
it is also displaying what your favourite weapon is.

The in game controls are easy to maneuver and is easy to get used to.
If you want to play online either in co-op or in versus battles there are plenty of servers in different locations so you can use the filters to browse for servers that is filling your recuirements of ping, difficulty, game mode and so on.

If you have any questions or any issues or maby even a bug report then you can just contact the devs via twitter, facebook or the steam game forum page, they are really fast at responding. and they are also really friendly.

i have already reported in a few bugs that aint a big deal and they responded within 20 minutes.
so i give the support area an 10/10 points just for that.

One of the biggest thigns about this game is that even it is a futuristic/sci-fi game it is still really realistic wich means things work out in the game as it would in real life, as an example: laser aim. in many games they make the laser beams a solid red beam that is highly visiblie to all players. but i real life you would not be able to see the laser beam unless theres some dust particles in the air. the more dust particles in the air, the more visiblie the beam gets.

and in the game. it is just slightly visiblie as it is under normal circumstances in real life.

the flashlight is dynamic light. it fades over distance and lights up the room like a real flashlight. it is not a static/flat light.


when you run, your character starts breathing more heavily. and starts to run slower.
if you get injured. your vision will become blurry and you will have an hard time to see your surroundings until you recover.

in the interview of the devs they say they wanted to create this game as realistic as possiblie for sci-fi games. and they did it pretty well!

in general this game is a whole lot of fun and really exciting and it is a great game and personally i have high expectations for this game as it got such big potentional to become something big and if you like fps games. then this is the game for you.

in general i give this game an 8/10 points.
reason i do not give it 10/10 is because of there is a few bugs, but im pretty sure this will be fixed pretty soon.
the campaign does not have much of an "story" but this is just what i like with games.
the multiplayer part is 10/10
but as i said earlier. this is still an early access game. so it is not done yet and it will improove over time. it is a good buy and i do recommend this game.

this is one of the best FPS multiplayer games made in a really long time.

Lock'n load. and prepare for having some real fun !

(i have made an in game video wich i will post up here pretty soon)
and ps: excuse my english grammar, im not from an english speaking country ;)

heres my video reviev in game:

What will it be?

A sci-fi, story driven tactical coop FPS.

What is it now?

Systems are incomplete, no campaign, but there are good coop PvE missions and team PvP.

How is it different?

Darkness. Real darkness. Clever flashlight usage needed. Scary.

Bots. Real bots. Scary.

Controls. Good controls. Holding a key holds, 'hitting' a key toggles crouch, aim, flashlight, laser. Hold time determines jump hight. Inventive, user-friendly.

Teamwork. Needed. Do not reload at the same time. Cover all angles. Assign roles. Use voice comms.

Is it fun?

Yes it is.

What else?

Community is quite mature.

Game has quality and polish already.

Developer is independent, crowd funded (before KickStarter!).

If you look at the hours I have put into this game that is pre alpha, you will see that I am continuously and thoroughly enjoying this game as it develops. I am eager to finally play the finished version no matter if it is still some time away. This game has taken me through a variety of emotions from fear, frustration, elation, and more. All of these things make it fun and challenging. It takes some time to get used to, because of some of the pre alpha anomalies. It is like a new pair of shoes. They look good, but when you try them on, they don't fit at first. After wearing them for a while they feel great and become your favorite.

Some people have problems getting used to the game, or have issues getting it running on their hardware. Just stepping over to the community with these problems and you will find a very enthusiastic and supportive dev group and player base that offer up loads of support to get you through the rough patch.

This game has the makings of a great single player horror FPS, and a great multiplayer competitive shooter. Add in the ability to do multiplayer co-op, and it becomes an epic game. It has a fine balance between frantic shooter and tactical shooter. As I see the story plans unfold, I suspect I will be enveloped by an epic single player story when it is finished.

As long as this game stays on the current heading, it will become a classic that everyone will remember. I have so much fun with this game that I bought it for all my closest gaming buddies.

If you buy it based on this review, I only hope that you enjoy it as much as I do, or meet me on the server and let me help you work those new shoes in until they are comfortable.

The co-op is the main reason to play this game. This feels like what the Aliens Colonial Marines game should have been. It is great, intense and sometimes terrifying. Of course the game is still in developement which means bugs, low fps and generic first person shooter mechanics. The developers actually interact with the customers and listen to their input, which is a plus.

Overall, this is an interesting game that is very promising. It may not be something special right now, but it is getting there.

Interstellar Marines is a very good game with multiple modes to play on. I haven't complete any missions, however I was very close on the Starcrown mission. I found the community to be pretty nice in the fact that they give nice tips. The game's servers are empty but there are usually 2-5 full/ partly full of players.
+ guns are good
+ missions
+ controls
+ community
+ no game breaking crashing
The flashlights don't seem to work for me, and i can't see in some of the mission during the night times and pitch black stations. I also found that some of the maps are spawn killer haven. This isn't really a bad point, but i hope they add capture the flag, team death match, and king of the hill. I would also like a game mode where its the bots verus 8-16 players.
- flashlight doesn't work (for me)
- more game modes
- more missions
-a campaign for single player?

After 8 hours I think I've seen enough of what this game has to offer to make my own judgement on whether or not I would personally recommend it in it's current state. I was looking forward to trying it for some time and really wanted to like it more. I will definitely be checking back throughout the future, and I recommend anyone else that is somewhat interested in the game does the same.

Without getting into details, the developers and the game concept itself have had a rocky history going back to 2005, yet they continue to persevere. There are a lot of reasons the situation is the way it is but it just reminds me of development failures like Duke Nukem Forever. Ultimately, it raises a red flag to me because every single game I had ever hoped for that had such a long development cycle ended up being a failure and as such I can not recommend people spend their money on something that statistically does not have a very good chance at delivering on the promises it has made.


My favorite part of the game (and this is honestly kind of sad) is that you can open and close your helmet visor. So far it's pretty pointless, but during the more lengthy game modes I find that opening the visor makes the game feel much more immersive - and it also makes me feel like kind of a bad-♥♥♥ for some reason.

I also really like the tap/hold functionality for running, flashlight, etc. You can tap to toggle on/off or just hold it for the duration you want it on. It's a nice touch that I haven't seen before anywhere else.

Maps like Elevation show promise, in that the environment changes - on this map in particular areas of the playing field raise and lower. That was very cool and is a gimmick that the dev's should definitely try to cash in on.

The 2 guns look nice.


The first night I played I started with coop, playing each of the Survival and Elimination maps and the much praised Neurogen Incident map where we experienced the key-card bug and ended up wandering around for 40 minutes (our collective confusion was one of the most amusing things I experienced in the game). I enjoyed myself but it didn't take long before I lost interest.

The next night I tried single player looking for something more immersive, and although it was a bit creepier to not have backup I just found myself running from objective to objective running and gunning without much strategy at all (yes, even on the Neurogen Incident map).

Finally I tried the multiplayer, after about 10 attempts to join servers and 10 subsequent errors I finally got to play. I quickly found that 3-4 sloppy shots across a moving enemies torso was enough to get a kill, easy. My fondest memory was getting repeatedly team-killed and having to wait 2 minutes for re-spawn. Also, I was killed a number of times without hearing any bullets, seeing any enemies or noticing any incoming damage beforehand or even seeing a message about who or what killed me.

The alerts that appear if you accidentally shoot a teammate are a nice touch but since you get kills in 1-4 shots it's often too late to be useful anyway. The only thing that really differentiates enemies from teammates (when your visor is open or HUD is down) are some barely noticeable blue lights on their uniforms. Some claim this is to add to the realism (right, because a game where robots run at you at 150mph is realistic), but I tend to think the dev's have just been too lazy to make a slightly different marine skin.

Normally, I play games for a couple to a few hours at a time but I just had no desire to do so with this one as it quickly became redundant, regardless of the solo/coop/multi options and different game types that aren't really too dramatically different from one another.


What we have right now is a game with only 2 weapons, 2 enemies and a handful of playable maps. Reading through the development blog I see that it took almost a year for crouching to be implemented - this, among many other things, in my opinion does not bode well for the future of the game. People have provided me with reasons (excuses) as to why it took so long, claiming that it's more advanced than a typical crouch function, but they fail to realize that what it is is actually just a cover system, and I've played tons of games with cover systems, it's nothing new and I'm not impressed.

From a distance, the game looks visually pleasing, but if you actually stop to look at anything you find that it's all really quite bland and lacking in detail. The computer consoles, for example, have less detail than an unpainted plastic model kit. I wonder if that's one of the reasons they made everything so dark?

When you start the game you're thrown into possibly one of the most boring training missions ever without even really telling you who you are, what's going on, why you're doing the things you do, etc.

The AI is atrocious, but stupidly entertaining. I have approached groups of bots, shot one and the rest just stand there perplexed. I've seen 3-4 bots getting stuck going up a flight of stairs. I've had staring contests with a few bots that I'm pretty sure are supposed to be trying to murder me. Sometimes they move around a corner to try and hide from you, but they only go halfway behind the wall so it's still easy to shoot them in the side of the face anyway. They also tend to get stuck on walls and behind doors. The only thing that balances their stupidity is the fact that they can usually kill you in 1-2 shots which makes me wonder why the marines even bother wearing body armor.

There are a number of silly animations and sounds which I'm sure could be improved rather easily. The running animation is as comical as can be and there seems to be an issue currently causing marines to suffer from rather serious sounding asthma attacks. I find it funny how you can kill someone who is standing perfectly still and their weapon goes flying like there is a really powerful wind or something (if you don't believe me, go to the physics playground, shoot the marine statues and watch the guns fly).

I see a lot of people saying this game is scary, granted the maps are generally pretty dark and robots run at you ridiculously fast causing some jump scares. It is creepy to hear their footsteps in the distance and wonder what direction they'll come from. I would still consider Mass Effect to have scarier moments and that was not a scary game. Still, there's potential for that to improve.

Final Thoughts:

At the end of the day I wouldn't have high hopes for this game, it has taken the developers a very long time to come as far as they have and they have much much farther to go if they want to achieve the "AAA indie" game they keep talking about. In my experience, a game that takes forever to develop is most likely a game that will never deliver on the promises it has made, or it will be ripped off and done better and faster by somebody else.

The game that aliens colonial marines never was.

this game is insane, at first it appears to be the standard fps senario where your invincible and you fight off a stupid amount of enemies. if thats want you want from this game then your going to get a suprise because this game is so freaking scary. i completed alien isolation, and yes that was very scary, but this so much more terrifying 10/10

"When is the next update?"
"Next update."
~ ZPS.Bozar (the community manager) answering my question.

Alright, now for an actually correct review.

This game first of all is in Early access, as you may have noticed already. Surely some of you might think "Oh great, it's another one of those sh*tty games where people are only begging for money, instant downvote." okay, no, it's not as bad as it sounds, in fact, the game is quite decent even though it's a Unity engine based game, and I don't blame them for using such an engine, knowing how they got bankrupt a few years back. So far I will only say the game is in decent condition, not that many gamebreaking bugs, some neat coop and gameplay experience, and it's filled with good people (except for me, I am the biggest ♥♥♥♥ of the game... probably), the community is mostly lively, and one of the devs (A.K.A. ZPS.Bozar (the community manager)) make Monday and Tuesday (possibly Wednesday even) community gatherings to keep the community updated with what's going on, what are the plans, when will be the next update coughnextupdatecough, and some off topic randomness with a couple of good laughs and shooting eachother in the faces, because hey, that's what the game is about.

Speaking of updates, yes, this game gets updated monthly as soon as possible, while almost 95% of the updates do get delayed due to some bugs and glitches that seem to pose a threat on what the gameplay might end up like (stuff like missing keycard spawns in which they don't spawn at all, waypoint breaks, AI errors, falling through stuff and so forth), personally, even though the devs do put up annoying delays which just make us wait a few additional weeks for a hyped update to come out... and thus likely crash a train labled "Hype train" full of innocent people who are only looking to see what the game has to offer. But still, the devs always do it for a good cause, they want to make the game as solid and stable as possible, whilst also give a few balancing tweaks to make sure that no one is overpowered in any way, so that's always an up. And besides, all the scripting and modelling and animating and map making is not as easy as it sounds for a small dev team, really.

But now, onto the fun stuff: The gameplay.

The gameplay is pretty solid, you are brought in with so far two guns (an SMG and an assault rifle, more are on the way, so give it a wait), at 7 PvP maps, all with a constant changing enviroment and increasingly good atmosphere, which will always keep you on your toes. Several singleplayer maps which can be played in coop on certain servers (more on that later on), and right now, a gamemode called Deadlock (before it was Deathmatches and Team Dominations, though these will also be brought back soon enough in the later update). Personally I like the Deadlock gamemode, it's an onslaught of an 8v8 (if you're lucky to get in a full server) where the two teams have to either capture all of the 7 points or eliminate the entire enemy opposition before they lose all the zones or get mauled by the enemy force. It's like Insurgency with Skirmish, capture a point to get your team back, although in this case, it respawns only one but (hopefully) useful teammate which has died before, which is always a good thing to do, because having the enemy outnumbered is a always an up for your team, although, just because they have only one last marine standing (or LMS for short, that, or "That guy who is gonna die and fail our squad because he has no idea what he's doing.") can always, and I mean ALWAYS, make a turn to the game where in the end it's YOUR team that gets outnumbered, and guess what, it wasn't because your team sucks, it's because the enemy team knows where to go first, where last, where the enemy might be, what point to cap, where to camp, and so forth, it's all basically tactics that bring this up, and that's the best part, there is always a way for something to go right or painfully and horribly wrong, and the game can easily be twisted by a single person's actions, wether was it a point capture or an enemy neutralization... or just smart corner camping, HELL, ANYTHING GOES BASICALLY. But mainly, it's the teamwork that keeps the team rolling, covering certain areas to prevent flanking, reviving dead teammates next to you (did I tell you that there is actually reviving in the game? Well, I tell you now, there is reviving in the game, use it dammit) to keep the odds against the enemy, and usually an accurate aim and some good reflexes will be able to get you out of the frying pan (and possibly into the fire if you're unlucky enough...), even though some people say it feels a bit like CoD coughgodieinafirecough and a bit like quake, well, I might have to agree there a bit, it does have a slight feeling to it, but never too much, as one going CoD style against the enemy will have him killed and his team to utter failiure (never underestimate the enemy, they can always appear smarter than they look). As for the AI of the game... weellllll... let's just say they still have a lot to improve with their robots, since they're buggy as hell (running into walls, shooting at people's feet, staring at the sky for no apparent reason, did I mention running into walls?), but nonetheless always fun to play against on harder difficulties (Realistic is the highest difficulty, just so you know, and I recommend that difficutly to be palyed at all games and times), beacuse it will always give you more of a reason to use cover and move around slower, because a few shots means death. So yeah. Speaking of dying, headshots are always instakills, so keep your head somewhere safe at all times... no, not underneath a bucket you baka. In the new update they introduced a stamina and accuracy system, which will obvously affect how you aim and such, so don't run around too much or you'll be hitting everything but your target, plus, you'll be moving with the speed of a snail if you drain out completely, you have been warned.

But what are the singleplayer/coop games like?

Well, so far there are 2 campaign mission, The Neurogen incident and Starcrown aerospace, which are both pretty good, even though Neurogen is a little bigger and darker, which is always good, while Starcrown is basically "Take that keycard to open that door so you can get a keycard to open that door so you can then pick up the intel thingy that looks like a keycard so you can open the evac zone and spawn tons of annoying robots which will blow your head off in a split of a second." ... That could've been better said, but sadly, I am being honest here. The Starcrown map is basically taking keycards to open doors like all the time... Still it does give the option to go through several enterances (Front door (my favorite), a side enterance at the left (which somehow looks more like a lobby...), a giant hangar door at the back, and a very convenient fence opening on the left storage area) which does give a little more variety to what ways you want to do this, always an up, even though in the end you end up Rambo-ing out to the evac zones with your friends, nevertheless a good laugh of constantly getting shot at. There are also several other coop maps, 2 Elimination maps (Mainline and Stronghold) in which you have to kill all the robots to win, 2 Survival maps (Colony and Operations) where you have to turn the power back on (CONTRADICTION + SPOILER ALERT: You actually end up turning the power off, not on, if you get the idea), and avoid getting killed by all the robots, and lastly an Escape map, in which you gotta get topside by doing some simple objectives.

Welp, looks like I'm running out of space to type stuff, so I'm just gonna conclude this with a "Must have!". I would've typed in so much more if I had space, sadly, Steam hates me. :C

Buy this game, buy the spearhead edition, support the devs, and I get a cookie. C:

Please note: In the interest of transparency, this was originally a negative review. I was unhappy with the game and it's progress and could not in good conscience recommend it at one time. However, the devs have lived up to their promises and the new review reflects all their hard work and a game that, IMO, lives up to it's price point on what it has to offer.

I must say I have been pleasantly surprised by IM's creators. They have recently churned out quite a bit of content for all modes and it's enough to give the non-deathmatch loving supporters something else to do. The shooting mechanics are improved with stealth aspects to the game, solo is very difficult and Co-Op a challenge worth playing. Better be in top form or you won't make it.

Don't get me wrong, IM still is missing a ton of content, most notably the actual sharks, but they've produced enough content they should be given the benefit of the doubt that it's coming. v If you own this and walked away, dust it off and try again.

If you don't own it just know IM is a twitch shooter with tons of potential and great backstory/atmosphere. The developers seem very involved with the community and have been producing lots of updates in the last year or so. I recommend trying it when comes into your price range.

I have been wanting to play this game since that first trailer released around 2006 and now that i finally got my hands on it I can see that it delivered everything I could ever want except for that cool mech and those muscle sharks. I was 10 when the first trailer was released, I am now 18 still waiting for this game to officially be released.

+Nice tactical gameplay
+Great immersive atmosphere and looks amazing for a game running on unity
+ Has this Ghost Recon feel to it (the good ones)
- NO MUSCLE SHARKS (as of yet)
- RUNS LIKE DOOKIE WHEN IN OUTSIDE ENVIRONMENTS (ranging from 21fps-60fps your experience may vary)
- Its hard to tell if stealth even works in this game since enemies tend to notice you wether you use a silencer or not
