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.

Ce jeu est absolument EXCEPTIONNEL ! Une ambiance Alien qui se ressent et qui fait franchement plaisir. Des monstres variés, au gameplay très intéressant, et une map convainquante. Pour moi, c'est un grand oui ! Hâte de voir la suite du développement du jeu.
MUY BUEN JUEGO

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.

Дуже прикольна та цікава гра, щоб пограти з друзями. Але також є можливість піти соло - і тоді це буде ультра-хардкор 0.0 Класні атмосферні локації, чудові звуки, які дуже добре доповнюють космічну тематику та й графон теж супер. Моби цікаві й усі різні. Перші 5-8 вилазок на корабель буквально відчуваються як робота детектива Особливо цікаво спостерігати, як усі всираються на перших вилазках. Квести різні, у кожного є свої ускладнення та сума, яку вам за нього заплатять. Прокачка легка й зрозуміла, ще великий плюс - можливість модернізувати свого персонажа, костюм і шатл. Динаміка гри - топ. Дуже сподобався квест із підривом об'єкта. Це було потужно, відчуваєш себе як у VR: серце б'ється, руки пітніють, ніби ти зараз перебуваєш у цьому місці та треба рятувати свою сраку. Дуже рекомендую до купівлі! Треба брати, поки гра в дочасному доступі, тому що потім, як я помічаю, ціна буде приблизно втричі вищою. Шкода, що про цю гру майже не говорять. Ми з кентами знайшли її абсолютно випадково, а вона виявилася прям супер цікавою. На вечір із друзями - саме те, що треба. Одним словом - кайфік
This game is peak, needs more time to grow and develop but even now in EA its well worth the 10$. Each monster is special in its own ways and has you thinking or saying "I did not expect that", and while its not perfect it is a very solid multiplayer survival 8.5/10
For $15 aud, money well spent.
very fun , scary at first run but you will get used to it
Great game with lots of potential. Can't wait for more development!
I came into this expecting phasmophobia in space but this game far exceeded those expectations. Featuring The Crew: [spoiler] The Brain Surgeon The Murderator The Breather The Attention-♥♥♥♥♥ The Poker and The Mystery Man (I have yet to see this guy after 20 missions) [/spoiler]
♥♥♥♥♥
