Early Access Review
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!).

Early Access Review
"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:

Early Access Review
Let me start my review by saying this game is not complete quite yet, but as far as I'm concerned, it mind as well be a full game.

In essence, Interstellar Marines is a tactical FPS simulation game with sci-fi and mild horror influence. Even though there are some premises and technology that are currently not existent in modern day, it feels realistic. I feel like that in ten years or so, this is could be reality, especially with good physics, annoyingly lifelike recoil, pain and exhaustion wobble and other environmental effects on your condition and visor. The 'realistic' difficulty is certainly true to its title: it is a true challenge to complete tasks with that difficulty active.

First off: gameplay. As of yet there are about 10 singleplayer missions of ranging objective, such as escaping a space station, clearing an area of hostiles, or restoring power to a building. In every mission you have two long weapons (no handgun, which I am not personally happy with) : one for longer range sniping, and one for fast, full auto, close range bursts. Recoil makes handling both of these weapons a great task, especially when scoped in. A silencer, laser and flashlight can be utilized at any time. The enemies are (in every mission I've done so far) robots. They have fairly good AI, and can be pretty fearsome when charging out of the darkness with ear splitting shrieks and slamming you around. They can recognize your flashlight and triangulate your position accordingly. Some are armed with weapons similiar to your own, and some use only their limbs. As for co-op/multiplayer: it's amazing. I love it. Some of the best co-op I've ever played in any game, ever. The tactical potential is immense. Working with your team mates to complete objectives and eliminate other players or robots is the best feature of this game. Nothing to be missed there. I personally much prefer the co-op to the multiplayer, as objectives often seem distorted and chaos seems to ensue in player vs. player scenarios. It is also frustrating to be killed in dark maps, where your enemies may be in a shadow, so they are invisible (or practically so) to you, but you are standing under a light. There is also no spawn protection, which can also prove to be aggravating.

Secondly: graphics. Absolutely stunning. The vigetting, superb textures and smooth atmospheric lighting truly makes this game a joy to look at. Some of the best lighting work I've seen in a long time. The way that each map has it's own feel and atmosphere is almost completely a result of the fantastic graphical work by the developers. 10 years have obviously been put to good work. The sound design is also very good. The maps are dynamic, as they change weather, time of day and general status (emergency lockdown, totally silent, in tranisition, etc.). In each mode, the sound adds very well to the atmosphere. The sound of the rain is consistent; robots' groans and creaking adds to the tension and fear of a startling encounter; the overwhelming sound of gunfire accurately represents how an actual warzone would sound.

And now, the conclusion.
Singleplayer --> 8/10
Graphics --> 9/10
Co-op --> 9/10
Multiplayer --> 7/10
Replay Value (singleplayer) --> 7/10
Sound design --> 9/10
Overall --> 8/10. Fantstic game, would recommend to any sci-fi/simulation/FPS/tactical fan.

Early Access Review
To be completely honest, I didn't buy this game, I invested in it. Several years ago they had a promotion for people who spent a certain amount of money to obtain "stock" in the company. I was one of those people. (I had to sign paperwork and mail it to them.)

This was all before it was ever greenlit on steam. Now, a lot of people say that it's slow or it won't be finished. Most people compare a small time-frame of from EA release until now, or an even shorter time-frame of "Free Week" until now. What I compare is literally from the time I invested in it, it was a browser-based unity engine, without an actual "client" to now.

Then, it had a few things to play around with, empty maps to explore, the visor, changing weather/day-night cycles, etc. Now it has multiplayer, coop, an emerging "campaign," and even some fun little things to find in some of the maps. (Personally found one of the shark models and took a screen-shot of it.)

While a lot of Early Access is considered failures or scams, eventually being abandoned by devs, I don't believe this is one of them. Sure it's slow, but how long does it take a AAA company to pump out a mediocre game with teams of 100s of people? Two or three years? This game has less people, and are working on a level of immersion I have yet to see in an FPS. I'd say that would take a lot of time.

Now, call me crazy, maybe I wasted hundreds of dollars, (Yes, I spent several hundred dollars), but I am excrutiatingly picky about games I buy, and even pickier about games I "invest" in. To date, only one of them has "failed" me, and that's Star Forge. Should this game succeed, I can see it changing the face of the FPS genre from here on out. A lot of "new" FPS's are simply revamped graphics with the same content. This one promises to introduce new "features."

Bottom line:
Don't buy if you are: Impatient, don't have faith in Early Access as a general rule, expect a whole lot of content right out of the box (current box at the time of this writing)

Do buy: If you actually read what I wrote, are willing to place faith in a potentially genre-changing title, don't mind slower updates.

Why: Because no matter if you buy it now or not, if the game fails, it's impossible that you will have wasted as much money as myself (Unless you also bought into the stock option back then, in which case I was on the lower tiers).

Early Access Review
This is a great game with good devs that actually took their time to deliver without many issues. I remember playing the test range in Kongregate some years ago (Bullseye I think) and Immediately knew this had potential.

I'd recommend this game to those that like to spend just some time on a game and then for some coop action.

'Quick' & simple review:

Pros:
  1. Dedicated developers, even if progress on the game is slow. (For goodness' sake, it's a small indie studio!) Plus great community managers!
  2. Generally mature, close-knit, and wonderful community.
    (I must warn you, a few black sheeps exist.)
  3. Intentionally challenging game mechanics: (devs are aiming for realism)
    • No HUD crosshairs,
    • real weapon recoil,
    • hearing impairment after taking damage (with disabled HUD until you recover),
    • dynamic character breathing (which affects gun wobble),
    • limited movement speed and hampered jumping,
    • no checkpoints/save system in campaign/co-op
      (aka. permadeath, 'cuz it's hardcore),
    • long respawn time in PvP to force the players to be vigilant,
      (you can never be too careful in this game)
    • fair & balanced PvP
      (for now, SMG and rifle are available, and NO KILLSTREAK BONUS, HA!),
    • bots are literally robots who can flank you, snipe you a mile away, and make you wish you are wearing adult diapers on harder difficulties.
  4. Innovative game mechanics:
    • First-person simulation
      (no floating hands, no viewmodels,
      full first-person body is rendered where FP camera resides... and that helmet faceplate you see in first-person?
      Yep it's a real in-game, in-environment model too)
      wtf, the HUD too?,
    • dynamic crouch & cover system,
    • changing environments and game states.
  5. Dynamic maps! (This deserves repetition!)
    (Laugh as a wall rises to block your opponent off, or ragequit when a ninja jumps on you.)
  6. Awesome audio & visuals!
    (Provided that your hardware can take it and max out all the settings, and it's in Unity.)
    • Hear the water splatter around you at different places
      (on the ground, on your helmet, on the roof...)
    • Watch how the water splatters on your visor
      (hint: slowly look up and down... if you bought this game)
    • "...help..." (Officially denied by the devs & CM)
    • Check out the lighting!
    • ...and maybe many more fine details that are too damn obscure that you must pay attention to actually notice.
  7. Tense atmosphere in both campaign/co-op and PvP.
    (Your flashlight may or may not be your best friend.)

Cons:
  1. It's Steam Early Access.
    (not really a bad thing, but I guess some people don't like the notion of buying an incomplete game.)
  2. It's hungry for hardware, and not Mac/Linux-friendly ('cuz OpenGL and Unity).
    • On my iMac:
      30-60fps main menu, 15-30fps in PvP,
      drops to 1-5fps on NeuroGen Incident (biggest map in the game)
    • *turn off beamsync*:
      OVER 90... yeah... until NGI, it drops to 5fps
    • Switch to Bootcamp Windows 7:
      40-100fps main menu, cool 30fps in PvP, 20-30fps on NGI... not bad.
    • *switch from DirectX to OpenGL*:
      screw this... OpenGL & Unity hate each other.
    • Machine: Intel i5 2.5GHz, AMD Radeon HD 6750M 512 MB, 8 GB RAM
  3. Plenty of bugs to stomp (which I actually enjoy, but then, again…)
    • I mean, check out the pinned post I'm keeping (or I had been keeping) in the Steam Discussions page. It's friggin' long...)
    • Seriously. The list, although unofficial, is longer than this puny review. The official buglist is much longer.
    ("...where the **** is the keycard?!" "HOLY CRAP I AM FALLING THROUGH THE MAP!"
    that kind of thing. But a marine keeps his cool, no?)
  4. Server rollback has yet to be coded & implemented. (keyword: yet)
    • Client-server feedback latency may vary for different people.
      If your opponent/robot manage to shoot you in the head before you can even react, blame lag.
  5. Small multiplayer population + surplus servers + high ping (in my area)
    • Perfectly good money wasted on empty servers, IMO.
  6. No landsharks, yet.
    • Devs are so perfectionist that they want to perfect the AI code before introducing the sharks... *hype dies out*
  7. Spoiler: Not in space, yet. (The NeuroGen Incident is a reenactment underground.)


Thus, in the current state of this game:

Recommended For:
  1. Gamers looking for a highly balanced and tactical FPS.
  2. Gamers looking for thrills with replay value, and tired of mediocre jumpscares.
    (Advice: Never play on Easy mode. It kills the atmosphere.)
    But this is not meant to be a horror game. It's... uhm... a test!
  3. Live by the game tagline: In space, your friends can hear you scream.

Not Recommended For:
  1. Gamers used to and prefer mainstream FPS, like CS, CoD, BF etc.
  2. People who don't like buggy and incomplete indie games.
  3. Gamers who set the same high expectations like they do with heavily funded games by big publishers.
...which I can totally understand. This review is meant to help your research.

Conclusion:
All you have to decide is
WILL YOU BELIEVE?

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.

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.
GG DEVS AND KEEP IT UP!
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.

BEAUTIFUL!

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:

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.

THE GOOD
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 BAD
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?

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

Just keeps getting better with every update, them robots....my god...scary stuff. A lil bit overpriced considering its early access and state, but worth picking up down the line once they have gotten further into development. Really good shooter, like insurgency but with space and robots xD.
