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 2,420 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.

Just wow
one of the best games I've played with my friends and we all enjoyed every minute when we all first played the game for the fist time we didn't know what we needed to do cause of the doors was locked we played the first mission for 4 hours straight just to find out to go to that locked door we got to go to the vents and we all cried finding out we wasted all that time XD enjoyed every second of this game
Игра в целом интересная,но маловато разновидностей монстров!!!
Excellent game. Went into this expecting some janky friendslop and was pleasantly surprised by the level of polish. Great replayability and captures the vibe of classic sci-fi horror perfectly. Fans of Alien Isolation will love this. Strongly advise going in blind and experiencing it for yourself to get the most out of the game. Currently there is only one (quite large) map set on a spacecraft, but the layout is intelligently randomised through the use of locked doors and varying objectives, and with the variation in enemies, you never quite know what to expect. Even when you do become familiar with the specimens, the game manages to keep things feeling tense. Circling around server blocks in a confined room while a creature lurks around the corner never gets old and captures that classic 'Alien' feel. For £8 this is an absolute diamond in the rough - a complete steal. Could easily be worth more! Very much looking forward to the new map coming in October, and to see what else the devs have in mind. Running this on a relatively high end PC, and it runs (and looks) excellent.
This is so much fun to play. Each creature has its own methods to avoid detection, fight back, or survive. There is an unspoken tactical element, a lot of general chaos when things hit the fan and it's amazingly fun with friends.
This is by far the best coop game to come out in the past decade hands down.
