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.

Very cool game with lots of potential. Very clearly early access, but worth the price. I am very much looking forward to where this game goes.
{
fun and scary however the "puzzles" (more-so fetch quests) to complete objectives consist of "walk around until u find out what ur meant to do" and that leads to some explorations taking 20 minutes longer than they should simply because u missed a single room in the corner - pay VERY close attention to ur minimap the monsters have real challenge and it always feels like youre teetering over the edge towards death good game 8/10

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.

You liked alien isolation? You have friends? You dont have friends? This game is perfect for you,
I like yeah
Only played solo thus-far. Have yet to convince friends. But it's great, I'm loving it. There's obviously a few downsides to Solo, main ones being the specimens like the Robot. Avoidable but because it targets 'Isolated targets' that's uhh.. you. But it's still super fun. Basically Alien Isolation if it were Co-Op. The AI even sticks around you like in Alien Isolation. Which I personally think is fun, makes it more tense. But would be nice if they ran away now and again to roam the ship but I assume that happens in Co-Op. Hopeful for more maps! Randomly generated maps would be ideal but the devs clearly put a lot of detail into the current one so I'll trust them. I do also think Solo play should be pausable, the devs said it goes against their vision but I don't understand that. It's solo, how are you going to abuse it? Who really cares anyways. And for people who say "go into the lockable rooms" what about with the power debuff? Go for a leak, come back dead. Yeah wow.
