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

Great co-op horror game! Yes, there is only one map currently. However, there is 4 different gameplay "modes" and 6 different creatures that do change how to approach each mission. This game has great potential considering it is in early access if the only negative is the one map. Good ambiance, good scare, and good replayability. Absolutely worth the $10
super great fun time nice job
Развлекуха для компании друзей, берешь миссию и не знаешь какой монстр будет на этот раз, в игре так же можно ломать голову, помимо нужно искать предметы, оружие, оружие которое нужно для монстров, кому то это плюс кому то минус не всех монстров нужно и можно убивать, так же можно строить тюрьму на корабле и на базе и ловить этих монстров, короче суть игры скилуха и скил мозгов, просто тупо бегать не получиться, у каждого тимейта должна быть своя роль, можете хоть в роли мясо бегать удачи !!! It's a fun game for a group of friends. You take on a mission and don't know what kind of monster you'll encounter this time. In addition to searching for items and weapons, you'll need to find the right weapons for the monsters. Some monsters may be easier to defeat than others. You can also build a prison on your ship or base and capture these monsters. The game is all about skill and brainpower. You won't be able to simply run around. Each teammate must have a specific role. You can even play as a meat puppet and have fun!
yes
Mid. Same map every time. Played fine yesterday. Won't even attempt to start today. Very annoying. Save your ten bucks.
Excellent jeu en coop, des missions bien sympathique, le vaisseau est grand de quoi faire de bonne session. Peu d'améliorations pour le moment mais suffisant pour commencer dans le jeu, nous sommes à 10h de jeu environ et comptons continuer. Graphismes au top et le jeu n'a aucun bug ou lag. C'est très plaisant même en early access d'avoir un jeu aussi opti. En attente de plus d'améliorations, de personnalisation, nouvelle map et peut-être créatures ou missions.
good
great game
buon horror misto tra dead space e alien isolation da giocare più in coop che single player più che altro per facilitarsi le missioni, ottimizzato molto bene non scalda molto sia cpu che gpu
