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

Игра, пожалуй, один из самых ярких и недооцененных кооп проектов за последнее время. Когда впервые запускаешь игру, даже не верится, что за ней стоит небольшая инди-студия. Возможности кастомизации, проработка персонажей, визуал корабля-хаба, дизайн заброшенного корабля и монстров выполнены ну прям на ОЧЕНЬ хорошем уровне. Да и в целом игра графически выглядит потрясающе, некоторые анимации и моменты поставлены на уровне ААА проектов. (если вообще можно с ними сейчас сравнивать, с учетом того, какое они в последнее время ГОВНО!) Заказы имеют повторяющийся формат, но при этом из-за гибкости геймплея ощущаются уникальными. Еще раз упомяну, что очень хорошая проработка монстров, как уже писали в других обзорах - Alien isolation на максималках. Иногда ты прям охотник, а иногда ситуация разворачивается на 180 градусов, и вы из уверенной в себе тимы превращаетесь в жалких собирателей мусора, которые судорожно пытаются просто дойти до следующей комнаты. При этом разрабы идеально поймали баланс эмоций. Игра держит в постоянном напряжении, подбрасывает действительно жуткие моменты, но не превращается в душный кооп хоррор. Она регулярно генерит запоминающиеся ситуации, которые впоследствии еще хочется обсуждать и смаковать. Настоящий скрытый гем, который однозначно заслуживает гораздо большего внимания, чем имеет сейчас.

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.

Richtig starkes Spiel. Spannend, unberechenbar und mit richtig gutem Monster-Design. Die Waffen und Ideen dahinter sitzen generell sehr gut. Optisch sieht das Ding für aktuell um die 5 GB hervorragend aus. Keine Ahnung, wie die das so klein hinbekommen. An manchen Stellen droppen die FPS allerdings schon mal auf bis zu 25 und es gibt spürbare Lags. Vermutlich noch nicht zu 100% optimiert. Da wäre noch ein Punkt, an dem man mehr rausholen könnte. Hoffe, da kommt noch richtig viel Content. So gepackt hat mich schon lange kein Spiel mehr – und das sogar kooperativ.
留給船員的警告 : 小心任何外星生物,尤其是有卡姿蘭大眼睛的那隻 !
Excellent jeu à faire entre amis, le design est top et nous plonge dans l'ambiance du jeu. La combinaison de la variété des missions et des différents "spécimens" offrent des scénarios très prenants. Bon potentiel pour la suite, on espère d'autres map, spécimens et missions !
Top game worth every penny hours of fun. great time killer with friends
Insanely good for an indie horror game, like everything is perfect except for the fact theres only one map, having generated maps would forever solve this issue, or atleast make 13 maps cause I assure you you'll have no problems playing this often!
Excellent co-op horror. The devs keep adding content and the sky's the limit with these guys. It is already really fun to play either solo or with friends, and the potential is immense.
It is a fantastic experience that kept me hooked from start to finish. The atmosphere is immersive, the mystery unfolds at just the right pace, and there’s a constant sense of tension that makes you want to keep exploring. The visuals and sound design work together beautifully to create a genuinely eerie environment, while the gameplay strikes a great balance between challenge and discovery. I can’t wait to see what the developers add in future updates!
peak game to run with your goated friends
Amazing game! It's in early access and it already has me hooked, can't wait to see more!
