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
Add-ons
Each DLC is estimated with the same model as a game, then summed — a modeled figure, not reported DLC sales.

Too few observations to say whether a discount moves this store's chart at all: across the last 30 days Steam · Top Sellers · Poland has just 18 day-to-day chart moves that followed a price cut, against 2,498 that did not. We are publishing the count instead of a direction — 20 is the fewest we will draw a conclusion from, and price collection outside the United States began on 6 August 2026.
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.

할인 할때 사시는게 적절할거 같습니다. 그리고 친구가 4명 이상이면 굿입니다 근데 저같은 아싸라면 차라리 안사는게...크흠크흠 무튼 게임차체는 매우 재밌습니다 잘하는 사람 만나서 버스타기보단 재미로 간단하게 플레이 하기 좋아요! 단점은....맵이 하나 밖에 읎으요.. 그리고 샷건 드신분은 오인 사격 조심하시길~ 친구가 죽여도 우리 함께 돌부처가 됩시다~
蹲蹲十月末的更新!我跟我的呆呆亲友们都很喜欢这款游戏!!现在内容还是比较少,但是十分的有潜力哇,氛围感很足,怪物的设计也不错。但是无数次感觉游戏里的枪械是个破摆设......最后,十分建议找朋友一起玩,独狼慎入!
complete sh*t mechanics. one small creature 4 people using electric gun-flame thrower-ice machine-shotguns and explosives. knocks down the creature 10 times. creature wakes up and one shots everyone while burning freezing and exploding. garbage.
fantastic game had a blast but learning that resets come from big updates means putting many many hours into it is a waste of time, if someone wants to "experience" it fresh they can start a new game catching some specimens was mind numbingly annoying and took most of the time that nobody can get back and all you get is an emblem that nobody is even going to see or probably care about. people working and living real life cant get this time back that was put towards earning the gear and especially the captures. But overall its one of the most unique games with top notch graphics and overall mechanics but if its going to be reset after reset ill have to pass on taking it serious especially when they think the time and effort everyone put in is only worth an emblem.
so fun even solo
I got this game for me and a few friends to try, since it had such a great price, And the trailer looks so good. I was expecting to get a few hours of fun out of it, and that would be it. But now I have over 40 hours in it now, and am active in the Discord, and waiting for every new update. I run a few sorties every day, and have an absolute blast. The creatures are fun, the gunplay feels surprisingly good, playing Solo or in groups feels entirely different. Being in EA, I wasn't expecting much polish, but this game looks amazing, feels smooth, and the play cycle is very satisfying. With a stream of new threats, areas, and new upgrades to get, this game could keep me going for years. Really good work guys, keep it up.
Really fun game to play with a friend. The atmosphere is creepy and there are some genuinely unexpected moments. The enemies can catch you off guard, which makes exploring a lot more fun (and stressful ). It’s an indie game, so there are still some things that could be improved, but I’ve been having a lot of fun with it so far. Definitely worth trying if you like co-op horror games.
