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.

Das Spiel ist leider sehr eindimensional und unbalanced. - Es gibt nur ein Level, welches jedoch VIEL zu groß ist (absolut extremst überdimensioniert) - Es gibt nur ~5 Gegner Monstertypen, die alle nach Schema F konzipiert sind - Die Monster sind sehr unbalanced. Viel zu schnell, machen zu viel Schaden und haben alle Wallhack. Oft auch ohne counterplay. - Es ist absolut nicht gruselig - Sehr reptitives und monotos Gameplay. Leider fetter Daumen nach unten. Außer es passiert noch nen Wunder mit kleineren, kompakten Leveln die gruselig sind und mehr Spieldynamik bieten.

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.

Balancing ist sehr schlecht. Alle Monster sind Tanks und wissen immer wo man ist. Es gibt nur eine Karte, die viel zu groß ist. Spiel fühlt sich leer an. Grafik gut
I tried to play the game because it actually looked interesting. When the game started it was just a black screen and nothing to do.
В игре ужасная система "Захвата противника" Суть в том что, нужно одному из игроков (хосту) всю игру копить 28.000 поинтов, чтобы открыть возможность "ловить монстров", а когда регаешь эти задания, вот напасть) Игра забагована и нет возможности запереть монстра. Все коммьюнити жалуется. что с 100-ой попытки получается обойти баг, а разработчикам класть Хотите поиграть? Игра прикольная, неплохая, но не вздумайте покупать улучшения для шатла позволяющее ловить монстров
Actually a CRAZY game for the price, its so good, fun,not too grindy and the ONLY thing that i dont like is that there is one map. Please devs, add new maps or maybe make the current HSS hawking bigger. get this game.
this game looks so good oml
good
Firstly, I just gotta say... this game is absolutely amazing. like 6/5 stars I swear. The game is so much fun, the graphics are great and when you really get into the gameplay... the game is so incredbly fun. The best part is that this game was just 10 dollars. I cannot believe this game was that cheap. I HIGHLY recommend this game. It is so much fun with other player... especially with friends and meeting others in the game.
Erken erişim için güzel, ♥♥♥ repetetive ama simdilik 10 saatten daha fazla oynatmaz bence
