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
There isn't much of a game yet, it only consisted of 2 guns, an assault rifle and an smg of sorts. However the atmosphere is really well done. Despite it's current simplicity the dark atmosphere and ability to shoot out lights to make it even darker is an unusual factor in the multiplayer FPS genre (which tend to have reasonably lit dark places or else supply night vision).

Along with the dark and deathly silent atmosphere you have enemies which are humanoid robots, however, as boring as that may seem, i've never had robots freak me out this much. Some of them are like fast zombies but they sneak right up on you before slapping you silly.

My favourite factor of this game is definitely the fact that you get the feeling you're the only ones alive. All there is is silence, that is very realistically unnerving when broken by sudden un-silenced gunfire.


There are some issues with objective bugs and flashlights not rendering from other players, i find the walking/movement to be a bit jerky and awkward, and as i said there isn't much content yet: limited guns, only 2 types of enemy with the same model, and fairly empty maps. While i like the atmosphere, i hope the game won't all be quite so barren and basic (when it comes to missions and so on). I guess i'll look forward to when this game gets some more meat on it.

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
PLEASE NOTE: Game Is in early access, meaning review could change!

One of the most realistic early access i have played. Right now their are only 2 coop missions and about 6 teamdeath match maps. The game slowly gets updated due to the developers have a really small team, but each update the game just gets better and better. This game is totally worth its money!

Pros
Add silencer on gun
turn laser sight on
Can open your helmet any time you want
Graphics are beautiful
Robots are a good challenge
Maps have a nice environment change
Can shoot lights out

Cons
Not many maps
Only 2 guns
Coops missions have the worst lag ever!

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
When looking to buy this game, you should take note of the fact that it is in Early Access. This means that the playable content is very limited. However, there are 2 large co-op missions, 5 smaller co-op missions, 8 player versus player maps (I think), 2 weapons (customization is going to be added in later on for weaponry), five movement speeds (crouching, walking, crouch-running, jogging, sprinting)... it is already incredibly advanced for a game in Early Access, and the developers play the game as well, to communicate with the community and see what they want, and have excellent presence on the forums.
There are some glitches in the game. Naturally; it's Early Access. However, there are so few compared to most Early Access games, or even FPS games in general, that it's almost mind-boggling. Each update is extensively tested and prepared before it becomes available to a small segment of the community - Spearhead testers - and are then further scanned for glitches and bugs before being made available to the entire community.
Many people had a bad experience during the Free Week, and gave this game bad reviews. Unfortunately, this is mostly because of people playing it on the Free Week only to annoy other players, and the limited customization available at this point. However, what many people don't seem to understand is that it is in Early Access, even though it entered Free Week; it's nowhere near complete, and rating it as if it were the full game is unfair to the developers and potential buyers.
Now on to gameplay.
When I first began playing the game, I went into multiplayer. DO NOT DO THIS. The game is so extraordinarily fast-paced that unless you play co-op and single player first, the people in PvP will be killing you so fast you'll suspect they're hacking - quick hint, they're not; they've generally played the game for literally days straight, and have become fifty times as good as any beginner. Don't think you can compete just because you've played other FPS games.
The robots in single player and co-op are still a tremendous challenge. Start off Easy and find that, without other people to revive you, you're dead in minutes. Two to five shots will kill you in Easy, and it only gets harder.
One thing I've found is that many people complain that Realistic isn't any harder than the other modes. Here's the thing: It is, but not for the reasons most people think. Yes, the robots one-shot you on Realistic. Yes, they have a shorter delay to begin attacking once they see you. Yes, they see you better in good lighting and notice you more quickly in bad lighting. However, the real thing that got me was that the closer you are, the faster they react; open a door and there's a robot immediately on the other side? You're dead.
In spite of this game being in Early Access, the amount of content already implemented is amazing, and the gameplay and realism of the game is incredible. So there are a few glitches and fewer weapons than you'd want in an FPS game. So what? It's still remarkably complete for something in this stage.
I would definitely recommend buying this game, and if you don't feel like it's right for you, check back in a month or two; the content increases with updates constantly. The results might surprise you.

Interstellar Marines is by far the most fun I have ever had in any game. Fight robots with your friends or go lone wolf. As of now there are few maps and guns, but despite that I find myself replaying the same map over and over again. This game allows you to use the environment and lighting to your advantage, and with the suppressors the game can be attempted from a stealth perspective. If you find yourself bored fighting with CTR's then go for some PvP. The developers are very active in the community and are concerned with your concerns. I will say that this game could be better optimized, so for those with low system specs, I would recomend waiting until it is released. FOR THE LOVE OF THE GAME!

How does the developer say that this is revolutionary.... If anything it may be another stereotypical sci-fi shooter. I had fun with it for about ten minutes, but they talk this game up too much, it's just another sci-fi fps.

This game has developed so far from the begginings when there was only 1 gun and jumping was not even added and there was only 2 or 3 maps. I bought this game in 2012 or 2013 i can't remmember more likly 2013 tho and ive watched it develop and in the biggining the multiplayer was buggy low frams and it was hard to play becuase of the charecter movment well now we've got co-op for that well edleast the big map co-op missions the smaller maps are fine but more optimization would be nice. What drew me to this game and is still one if not greatest feature is its weather machanics where your in a huge dome areana training and the weather will change. It differ greatly between maps such as some maps will give you a blizzard some will give you pitch black darkness and fire sirens with flashing red lights. But the guns and the movement are still very limited and you will find you charecter sounding like hes dieing if you run to much like e and my freinds are sure he has asma, the gun play and charecter movment has improved there jumping and suppresers and such but still you will struggle to move around fast some times and player can and will block you in hallways bye accident of not. And the missions i have played, like the Neurogen Incident were great and i haven't played threw everything. What i hope to see in the future for this game is better move ment better guns and better optimized for mac and pc users, oh and linux if it supports linux not sure. Over all its been a couple years tho move ment has been slow on this and i hope it will speed up a bit as we go becuase i remmember when patches would rarly happen but i would 100% buy this game unless you would like to wait and see how it pans out. My over all score so far is a solid 7.5/10. would be a nine but again the movment and the guns and the frams and its not just me.

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.

This game has a lot of potential to be a great FPS. The missions can get a little tedious after playing them over and over but the game is still fun. Co-op needs some work cause there are still bugs out there, it can get pretty damn laggy, and voice communication sucks as of right now. The graphics are pretty good, the sounds are decent, and the level designs are pretty cool, but nothing we haven't seen before in other FPS games. As of right now, I would give this game a 3.5 out of 5 cause there is still more work that needs to be done. But like I said before, this game has a lot of potential and I look forward to seeing what becomes of it in the future.

Interstellar Marines has alot of potential and good ideas. A good game that is very tactical and relies heavily on team work. I personally can not wait to see what this game will hold for us in the future.

I purchased this game via Steam over a year ago, and at that time, I was extremely disappointed with the product, even given the fact it was in very early stages. I randomly opened up the game today, and to my surprise, a campaign mission was available! The polish and immersion of this level was incredible, and I could not believe how into it I got. The servers are still woefully underpopulated making multiplier untestable, but at least they gave me a taste of what I wanted: an incredible setting populated with equal parts terrifying solitude and unnerving company, with surprising polish and rewarding gun-fighting. A little thing, but I feel they nailed the sound for a wide and reverberating space station interior. I cannot wait for the finished product, and am not only relieved at my purchase, but excited.
I Just have a copy of that game in my Inventory and I'm ready to trade with something that has the same value :)
If you want to trade with me, just send me a friend request and we'll find something to trade ^^
