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.
Updates
Build ids and update times come straight from Steam's PICS — the same source SteamDB reads. Patch history grows as we record new builds.

good game
10/10, for the price, the game, the sheer fear. I hate 005 with a passion.
One of the best horror games I have ever played. It is extremely well optimized and very scary. I would highly recommend you get this game

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.

Muy bueno para jugar con amigos
This is not a 10 dollar game, it's a 100 dollar game. The atmosphere, the visuals, the gunplay, the music and sound design, the specimens... breathtaking. It is more than easy to see that the people who made this game are passionate developers. This game just can't stop surprising me of how good it is. The optimization is great, the map is awesome and the overall gameplay is crisp and polished. Now of course not EVERYTHING is perfect, I don't like the suits for your avatar, they look kind of shallow and silly. The drones for the corrupted robot spawn in huge numbers, wasting your ammo quickly and finding you even if you hide. Besides that, I love it. Nothing that I find off about the game is a serious issue, and despite the problems I'll keep coming back for more. I don't know even how to explain how spectacular Species: Unknown really is, except for saying that is a must-play, especially for its price. The exploration, discovery and planning that you must make mid-mission encourage you to work together and think before you do. (What creature are we dealing with? What are it's abilities? What are its weaknesses? What is our mission, extract, capture, kill or destroy? How do you survive this room? What weapons do we need? Where do we head next?) All of those and many more are asked and answered, forcing you to move and think simultaneously. Do not let the low price tag fool you. It is worth way more, but the developers aren't greedy, sloppy delinquents like most, they genuinely care about building a thriving community that will help them shape the next game of the year. 10/10
This game is super good, looking forward on the updates.
