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.

Great game, just a bit more optimisation and a few QOL tweaks and we'll be in paradise as it grows. 10/10
This deserves more love then it has. It's better made then 90% of the games out there in steam. The only thing I got problem is that "corrupted Robot" that only flies around and actually only attacks when you are alone or he starts tweaking. I do believe that this boss has to be changed or atleast make him more harder because he is easy and boring at the same time. Otherwise good game

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.

Well worth the money. I've got 30 hours out of it and there's more content coming that will keep me engaged. For early access it's very bug free. Haven't had a crash or encountered any major issues. My PC is 6 years old, 2000 series GPU and runs fine. Can be played solo but more fun with a team, even better if everyone is on voice. The communication and teamplay adds a lot.
Игра супер, но мало контента. Дальше просто мои хотелки и идеи. Так что коммент не шибко важную информацию несет. Хотелось бы добавить в камеры содержания больше просторности и предметы(покупать специально для них. Хотя бы для животных. Вы так даже можете раскрыть лор субъектов). Лучше если они будут отличаться друг от друга. Просто смотря на тех же в камерах "Осьминожку" и "Создателя зомби апокалипсиса на корабле" становится грустно. По сути эти двоя просто животные. Смотря на их камеры ощущение печали. Если рассматривать их как реальных животных, то у них явно был бы стресс в этих камерах(особенно после поимки). Так же хочется каких-нибудь безобидных созданий, которых можно поймать/приручить и они просто будут жить на нашем корабле. У меня есть ещё идея, что когда ты поймал субьекты, есть ОЧЕНЬ мизерный шанс, что на корабле произойдет утечка и какие-то субъекты окажутся вне камер на ТВОЕМ корабле. И вдобавок, например, осьминог, смотря на сколько ты ему предметов купил(так сказать ухаживал), он будет более мирным или злым и напуганным.(естественно на некоторых такое бы не сработал и кто-то даже без предметов был бы просто злым) (Но смотря на эту идею, воплотить явно будет сложной задачей. Поэтому можно просто оставить как информацию, что такое может происходить)
i love the game and its realy good horror game
The sentry turret mission modifier is absolutely broken. Turrets appear out of nowhere with no rhyme or reason, popping up in places where they weren't beforehand, gunning you down in seconds flat. I will remove this negative review if the sentry turrets are ever fixed, but for now they are absolute ♥♥♥♥♥♥♥♥. Also, the zombie spawner is an absolutely terrible enemy, I'd rather have my arms and legs broken with a sledgehammer than deal with constantly respawning zombies.
super mais il manque un peux de contenu mais sinon il est top
Very fun with different aliens just wish there were more maps to give diversity
good fun game they are doing the whole wipe everyones progress ♥♥♥♥ so for that reason im leaving a id say 2/5 stars and some aliens aren't the most fun along side some aliens just randomly finding the player even tho they didn't see or hear them is kinda dumb
생각보다 재밌음. 근데 어느순간부터 업적작 하느라고 인간성을 잃어버림.. (야 시체 어케생김? 아 쉬발 똑같은거네 리트 ㄱㄱ)
