First, Massive Co-Op Mission Now Available!

Our huge first co-op mission, The NeuroGen Incident, is available now and propels you into the middle of a pivotal mission in the Interstellar Marines universe. Play single-player or co-op with up to three friends in intense action.

Set in a believable future, you take on the role of an elite soldier handpicked to join Project IM, a top secret military program being assembled to protect mankind from all dangers outside our solar system.

Interstellar Marines is inspired by Half-Life, System Shock 2 and Rainbow Six 3: Raven Shield. Our game is all about evolving the FPS recipe with all the inspirations we've assimilated since the birth of the genre.

Co-op just got released and holy ♥♥♥♥ please buy this game. It is the most intense terrfying multiplayer I have ever played in my life. I got online with a buddy and these robots stalk you, flank, change postions and do everything in their power to kill you. They also weren't designed to be terrifying yet they somehow are. They look human enough for someone to feel comfortable around them but the lack of facial features and the fact that they sprint full tilt at you when they notice you makes them horrifying. It is definitely rough around the edges as its a work in progress and if you have been worried about the long development time these people know what they are doing the shooting feels great, the design is amazing (fantastic lighting, weather effects, AI is almost perfect and the guns feel powerful) and these guys know how to make a games tense. No music just ambiance, enemies are almost always heard before they are seen, you never know if the robots or moving or its just your partners footsteps. This game is just amazing and they are planning to have SHARKS WITH MUSCULAR LEGS and tons of other crazy enemies and 27 weapons. BUY IT PLEASE

This game is ♥♥♥♥

Multiplayer: prepare to rage (If you find a server with players).

Co-op: Prepare to ♥♥♥♥ bricks. if you have thin walls in your house or are prone to heart attacks and shock, please be careful. I'm writing this just as I experienced the first co-op test. problem is that i did not invite any friends ;-;. Imagine being in a completely dark, sprawling hangar complex, with nobody to keep your sanity, and god knows how many robots waiting for you. And let's not even count the scare when you see a robot but aren't sure if it's dead. if you think left 4 dead or a similar game is scary, you ain't seen nothing yet. I can tell that this fear I just had will be multiplied tenfold when more enemies and missions are there. ♥♥♥♥, if there were good procedurally generated, dynamic missions, that would be craaaaaazy awesome (and bad at the same time).

Graphics are good, UI is amazing (Very realistic near-future/space age hybrid for the HUD) and the experience is unmatched. god knows what it would feel like to play this on an oculus rift. In short: if you buy this, make sure you get a 4 pack or more for some buds, because without that sort of teamwork with people you know, you'll be ♥♥♥♥ed by 10 different species of aliens and robots.

It's very hard to review this game because it frequently changes, and every tiny change drastically changes the gameplay experience, this is as of 10/2014. Basically it's a hardcore shooter, without the ♥♥♥♥♥♥♥♥ that you encounter in many popular shooters. Camping is pretty much impossible, objective play is encouraged, and the weapons feel like killing machines and not bb guns. Probably the best part I love about this game is that it has different atmospheres, let's say you play a team death match, and every couple of minutes the lighting changes, it may be fully lit, almost dark, flickering red lights, or full complete darkness. Full darkness. Raising your brightness won't help, it's completely dark. You got a flashlight, if you turn it on you're a moving lighthouse. It's pretty good.

Update 13 - Co-op. Worth it and just different enough to keep you playing. Progress is always being made.

The multiplayer is still very solid, and enjoyable. The game modes are different enough to not get boring even after a quite a few matches. The weapons are very balanced and responsive, along with the flashlight and laser they don't feel the same at all. Game has enough players to always find a server with enough people to enjoy yourself.

The co-op is really incredible, can't say how long it has been since had a co-op game where me and my buddies could really explore a level and attack the mission the way we would like to. Very large and open mission with plenty of interesting things to see and fight. The AI are quite smart, and will give you one hell of a challenge and a freight.

Performance is still on the rough side, but still making improvements to it on the regular, I maintain a regular 40+ even with the not so good areas of the mission that are very well unoptimized.

This game still of course has a long way to go. But for the money I feel like you very much get your money worth, with plenty of things to do and much to see. High replayability and enjoyable overall experience.

When I bought this game, I immediately regretted it when the game was nothing more than a few multiplayer maps that you could walk around in.
It has improved a large amount since then, with a co-op campaign being added. It looks like a good start to an atmospheric survival-horror game. Perhaps not quite worth the $20 at this stage since there is still very little there, but maybe in the future.

7.9/10 - Pants were ♥♥♥♥.

'Quick' & simple review:

  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.
  3. Intentionally challenging game mechanics: (devs are aiming for realism)
    • No HUD crosshairs,
    • real weapon recoil,
    • hearing impairment after taking damaging (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,
    • 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),
    • dynamic crouch & cover system,
    • changing environments and game states.
  5. Dynamic maps! (This deserves repetition!)
  6. Awesome visuals! (Provided that your hardware can take it and max out all the settings, and it's in Unity.)
  7. Tense atmosphere in both campaign/co-op and PvP.
    (Your flashlight may or may not be your best friend.)

  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).
  3. Plenty of bugs to stomp (which I actually enjoy, but then, again…)
  4. Server rollback has yet to be coded & implemented. (keyword: yet)
  5. Small multiplayer population.
  6. No landsharks, yet.
  7. Spoiler: Not in space, yet. (The NeuroGen Incident is a reenactment underground.)

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.)
  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.

Early Access Review
So far this game seems to be going in a great direction. The ambitious developers have been updating in good iterations and the background is looking very excellent. This game is essentially a Science-Fiction FPS where you are a Marine that goes to.. space! Common theme right? Well, this game does it different. You aren't some Halo Spartan or Warhammer Space Marine. You aren't some overpowered super-armored exo-suit marine that has access to giant guns and can punch enemies through a wall. You are a ordinary soldier who is trained for elite operations in space and ground.

This game puts a nice emphasis on augmented reality technology, such as implementing a visor that indicates your objectives, ammo, used items, etc. This may compare to other Sci-fi Marine flicks, with the exception that it is in such a way where the technology IS apart of your helmet, and not some typical video game user interface. Take off the visor and you will notice there is nothing. No recticule, no ammo type, no indicators for equipment, no objective points, NOTHING. Just your gun and it's trustworthy Iron Sight.

Right now as of Early Access, there are several features players can experience. While it isn't near to completion yet, it definately shows progress and I feel like these Developers are NOT out to dissapoint anyone. One thing I would like to see with this game is a little more of a team-based orientation when playing in competitive matches. It seems like no one really sticks as a team and it becomes a solo-festival of shooting. I don't have a big problem with it, but I have a problem if teamplay isn't encouraged.

What really gets this game my thumbs up right now is the whole immersive experience. The Ambient sound effects while on board a space station with the lights out makes you feel like a real soldier sent to investigate a dead space station. The eerie sound of hostile robots and their locomotion has you glued to the iron sight to check all areas. The Helmet is on, the gun is loaded, the objectives are displayed and the flashlight is on. Ok, time to figure out how to proceed to the objective.

This game just seems so much in that realm, and I would love it to continue being so. I just hope not all the levels are going to consist of pitch-black environments with 100% flashlight usage. The game should demand all sorts of scenarios. I do like the darkness, but I want a balance of dark and light. Missions in places where facilities have power and missions where places have no power and it is dark. Balance is everything when it comes to mission consistency.

Things I expect and would like when the game goes gold:

1. Peak performance optimizations
2. Plentiful amount of multiplayer and singleplayer missions.
3. Adherence to realistic player movement and team-oriented gameplay.
4. Adherence to that immersive charm that I mentioned.
5. Variety of equipment and weapons.

I have a great amount of enthusiasm for this game. Keep up the good work!

Early Access Review
For an early access game, this one has a fantastic amount of potential. I had the pleasure of having this gifted to me, and it is easily one of my more favorite early access games, and also a powerful FPS experience.

The aesthetics are awesome! The detail in the environment and two gun models is very good. The music and sounds are good - hearing bullets flying near and around you creates an extremely intense experience. One of the best features of this game, however, is the dynamic lighting effects.

During gameplay, the enviroment will change - in some levels, there will be an increase/decrease of elevation in certain areas of the game (allowing for sudden height advantages/disadvantages if you are in the right/wrong place at the right/wrong time). Even more impressively, the light will switch between day/night-time cycles. During night, you can barely see directly in front of you - and using a flashlight and/or laser pointer for too long may give away your position. Stalking your target, hiding, then killing them when the lights come back on is so gratifying! Different levels also have red warning lights flaring during the night-time cycle, and this helps a little bit with visibility. So far, I have not come across any other game with lighting effects on par with Interstellar Marines.

The controls are typical of an FPS and easy to familiarize yourself with. The tutorials are provided in short, informative videos provided within the game. The learning curve is minimal to moderate (and actually, to challenging) depending on your experience with the FPS genre. Now, I pride myself at being fairly strong in most competitive shooters, be it first- or third-person; however, I had a rude awakening when I first tried Interstellar Marines. The gameplay is so intense and cutthroat - you die very quickly (which I love), and it took me a few game sessions to find my bearings.

Another thing I love about this game is how your heads-up display (HUD) will turn off when you are near death. Considering that friendly fire is always on, it can make firefights very interesting if you cannot remember where your allies and enemies are. You can open your helmet, however, I do not really see a point of doing this (for now). There also is no melee at the time of writing this review.

The two weapons you have available is a close-to-medium-ranged submachine gun, as well as a longer-ranged assault rifle. There are no grenades to use. You can crouch, but not go prone, and sprint is already one (you can toggle it off). I am unsure if there is going to be a stamina mechanic, however, as of now, I think you can sprint indefinitely.

Overall, if you are an FPS buff, you MUST try this game. You will not regret it.

Definitely recommend!

Half-Life, System Shock 2 and Rainbow Six 3: Raven Shield had a threesome, and out came Interstellar Marines.

Very solid game that does one thing right that so few games do; look gorgeous and be immensely fun simultaneously.

This game is really quite good, the NeuroGen Co-op provides the most terrifying atmosphere in any game I have ever played. If you decide to try it alone prepare to crap your pants with every corner turned and cry your self to sleep. With that in mind I wouldn't say this game is only for people looking for a scare, the tdm and domination are dynamic and worth the play. 10/10 for an early access game.

Early Access Review
-Beautiful to look at (amazing lighting)
-Challenging and competitive multiplayer
-Unique "Deadlock" multiplayer mode
-Pace of multiplayer games is just right
-Well-designed maps
-Dynamic weather/time-of-day creates constantly changing multiplayer conditions
-New story-driven co-op gamemode vs AI

-Limited number of servers to play on/not able to start your own server
-Other things that are to be expected from an Early Access game, such as limited weapons/customization along with minor bugs/glitches here and there.

Bottom Line:
9/10... and we're only just getting started.

ISM is probably the most well-polished Early Access game on Steam. It is fully playable (and competitive) in its current state. All current issues with the game are things any fair-minded gamer should expect from an Early Access game. Limited number of servers is sure to change as game development progresses. Looking at both what has already been added, along with the concept art of what Zero Point Software intends to add, is incredibly promising. Gameplay is not quite as fast-paced as Call of Duty, but is not so slow that it prevents you from running-and-gunning when necessary.

Early Access Review
Crawling through air ducts I finally reach an opening and drop to the floor of the new room. I scan that area and see many toppled crates and racks. I hear metalic foot steps rapidly approaching from ahead and my left. The first robot enters then beam of my flashlight, I mow him down with my 30rd SMG. I rapidly try to find the next enemy, it's too late he's already on me. I open fire with what's left of the mag, the robot hits me and my SMG's aim moves towards the rafters. I backpeddle as he closes in for the final blow. *click* My guns out of ammo. Not 2 feet from me the robot takes fire from else where and drops to the ground. I search the area for who shot him, and in the air duct I dropped out of is another Marine.

This game is EXTREMELY atmospheric in a dark room with headphones, you simply won't want to play the campaign alone. It has elements of a horror with the setting of a sci-fi shooter. Enemies are fun to disable and teamates are a blessing. It is in early development so there are plenty of issues but finding ways around them and truly exploring the non-linear research station is a great feeling. Enemies are randomly spawned each playthrough so an empty room you opened last week may be crawling with CTR's the next time you open it. This crude mission makes me really excited for what ZPS is going to release next, and if any dev's read this I'd love to see a really badass futuristic double barrel shotgun. It's something I would have loved to have in my first playthrough for those stealthy CTRs.

Lighting in the future is doomed. 9/10
