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

This and every other Pro feature is free until October 20, 2026. A free account is all it takes.
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 · Poland over the last 30 days: the 21 chart moves that followed a price cut of more than 20% went a median of 12 places towards #1, and the 2,501 moves with no price cut behind them went 1 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.

This game is designed to learn and understand the creatures you'll be facing. It's great if you go in with this in mind. It's still in early access, and there's only one map, but it's worth the asking price. I'm looking forward to more content for sure.
El juego sus diferentes mecánicas hacen interesante cada partida, me recordó una mescla entre Dead Space y Alíen. la ambientación esta perfecta, los enemigos algunos son demasiado fastidiosos, pero es interesante como cada partida puede variar vale la pena traerse a los amigos y sufrir en conjunto.
Alien isolation и Dead Space в одном флаконе) о таком нельзя было даже мечтать, спасибо разработчикам за игру) жду новые виды и локации!

fun game
Scream and die in outer space.
I was not expecting this game to be so fun. Despite it being in early access and only having one playable map at present the gameplay loop is smooth and tense enough to keep me invested. The creature designs are cool and specific weapons and tactics are needed to handle them effectively. Their behavior patterns are perhaps a bit too forgiving, at least when playing coop. They typically aren't difficult to outrun, and staying alert and communicating well generally keep things under control. [b]Things I would personally like to see:[/b] An NPC or two back at base. A smaller or more purposeful base that doesn't feel so empty. A map tool upgrade that adds teammate locations to mini map. A healing tool upgrade that makes it also/instead act as an adrenaline boost. The tool doesn't seem very useful at the moment. AI refinement making it feel more like each creature is hunting you using its own innate attributes. Scent, light, and voice/radio chatter could factor in. Give creatures special abilities that make them temporarily more dangerous, harder to outrun, etc. More environmental factors that hinder or harm would be cool. Smoke, steam, toxic or flammable gas, etc. More variables requiring situational awareness and shift in strategy. Specimen database updated with new lore/info after each kill or capture, accessed independently from the viewing room. Blackbox data viewable at a terminal, adding ship/location lore. Completing destruction missions should also provide some sort of meaningful data or progression.
