About
Species: Unknown is a first-person survival horror game, playable in co-op with up to 4 players (private or public servers) or solo. You play as a mercenary sent aboard an abandoned spaceship. Your job? Execute high-risk contracts, make it out alive, and claim your reward. But keep in mind that you’re not alone. Something is hunting you…
Form a squad of up to 4 players to take on different contracts with escalating difficulty. Each mission plays differently depending on your objective, your teammates, the map and which of the 5 intelligent threats is stalking you. No one survives alone, but you can try.

Proximity Chat & Radio are available: distance matters, walls matter. Proximity Chat is bringing more tension, sometimes chaos, and unforgettable moments to your co-op sessions.

Every contract drops you into a different nightmare. Whether you're tasked with extracting a black box, capturing or eliminating an unknown threat, or even destroying the ship to prevent the creature from escaping… Each mission demands a specific strategy and none of them are easy.
The specimen is chosen procedurally from a growing roster of terrifying monsters. Each one comes with distinct behaviors, hunting patterns, strengths, and weaknesses. You’ll need to investigate your surroundings to gather vital clues and identify the threat in order to proceed smoothly (or not). Do your job and get rewarded, or die without anyone knowing.

Strategize as a group, make smart use of your tools that can turn the tide, if only for a moment:
Motion Tracker : Detect nearby movement and prepare for what's coming
Shield : Block deadly attacks and buy time for your team
Health Syringe : Heal yourself or allies in the heat of battle
Mini-Map : Navigate pitch-black corridors with real-time positional data
Guns won’t always save you. Some threats are too resistant or simply untouchable. But the right weapon, found at the right time, can help you push through or even take the creature down.

The higher the risk, the higher the reward. Completing contracts earns you credits you can use to:
Upgrade your gear
Buy new tools
Customize your appearance
Gather lore and build your own creature museum

Reviews, worldwide (the counter carries no country): 18.86/day in the week to Jul 31 → 19.57/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,515 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

One of the best co-op horror games , the atmosphere is awesome giving you real horror vibe the way you identify the spaceimen is unique . overall great game can't wait for the new updates
This game is great.
Insanely good for an indie horror game, like everything is perfect except for the fact theres only one map, having generated maps would forever solve this issue, or atleast make 13 maps cause I assure you you'll have no problems playing this often!
The good: Great gameplay concept. It's like Lethal Company meets SCP and I'm here for it. The controls are smooth and intuitive. The difficulty is sitting at just the right place. Not too hard or too easy. Some monsters will absolutely **** you up, and others are manageable. Once you learn the mechanics you're probably golden. The Bad: The direction is kind of wonky. The map is helpful, but it's limited, even with upgrades, and you find yourself traversing death traps to get where you are getting, and then learn you didn't even need to. But really that's mainly an issue for new people trying to learn the map. So while it's not necessarily a 'bad', it's something I feel I should throw out there for anyone looking to get this. So pay close attention to where you are going if you are starting out. The Ugly: There is currently only one map, but I will also admit it will likely change in the future with updates and content as the game is in EA and is still pretty early in the development. Overall I recommend the game. It's been fun with my buddy to play. I'd give it a solid 8.5/10 for the price and what the game has to offer.
игра крутая
This has to be the best early access game my wife and I have played! very excited for 1.0!
Good game but definitely needs some more time in the oven. The basic gameplay loop is Pick Mission -> Load In -> Power On Ship (one map as of now) -> Complete Puzzles/Objective -> Extract. The good parts are that its pretty well made, very replayable, and it can be scary at times. Each mission will randomly pick a monster to hunt you down, some are better and more interesting than others. You can tell what monster it is before it jumps you by looking at the corpses around the map, a detail I found pretty neat. You get credits for completing missions, which you can then use to upgrade yourself/gun/buy tools. You are also able to upgrade your ship and unlock a new mission type. I find that the upgrades are a great way to keep me coming back as I love progression. Besides upgrades, you can also unlock information about the different entities by completing missions, resulting in a room in the lobby for you to view the subject. Some of the monsters are pretty boring and finicky, especially the one that basically forces you to tongue kiss your friend the entire game (fun). Also dying even at the end of the level gives you nothing, I think thats a little rough for a 20 minute match where you finish all objectives except extract. Especially if your gonna do some bs like spawn the monster in the ONE hallway that you can exit the area from.
Game is so good even though its still developing. Game is very fun and has its scary moments and halrious moments. Can not wait to see how this game contiunes to turn out.
