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

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.

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.
The squid in this game has made me actually squid racist. This isn't a joke I ♥♥♥♥♥♥♥ hate squids now. Show me a squid I don't want to cuss out and I'll show you my whole butt
I love this game, but the only problem is that it's way too hard for my silly friends and me, and the game is quite short. However, it's an early access release, so I'm sure it will only get better.
This is a lot of fun, I cant believe how cheep it is. i only done 3 missions with 3 different creatures. but while the map is the same right now, the creatures are completely different, they don't just feel like a re-skin of the same enemy. So the missions feel different. also its pretty hard 4 of us and we failed 2 out of 3 missions :D Playing with friends this game is amazing and i cant wait to see where they take it.
All my friends died and I said "Don't worry I got this" but then promptly shot a canister and blew myself up. Excellent.

Jeu avec beaucoup de potentiel, mais beaucoup de problèmes. Déjà, vaut mieux avoir des amis pour le faire, c'est plus drôle. Le jeu est plutôt beau, mais terriblement rigide. La variété des missions est trop peu grande malgré certaines nouvelles mises à jour. L'IA des monstres est aléatoire en fonction des games et rend le tout frustrant. Le pire étant les collisions entre les alliés qui empêchent de courir dans les pires moments (et ça encore, c'est drôle parfois si tu te débrouilles pour que ton pote meure à ta place). L'ambiance des maps est en revanche bien travaillée et l'aspect détective Scooby-Doo pour savoir quel est le monstre est bien foutu. J'espère que de nouvelles mises à jour continueront, car le potentiel est là, mais n'est (pour le moment) pas bien exploité. 5/10
