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

Berbattt ötesi bir oyun. Korku teması dodgelenebilen yaratıklar yüzünden tamamen komediye dönüyor. Aşırı sıkıcıydı
A perfect match for alien isolation and phasmophobia!
if you got a crew of friends this is a must
I'm sad not many people know about this game. It's a great suspenseful co-op horror game. Only thing me and my friends wish for currently (other than adding more content) is that WE WANT JUMPING IN THE GAME.. We kept instinctively pressing spacebar to jump, only to bring up the minimap as we got mauled by the monsters... haha Please consider adding jump, this game would be soooo good with jumping and being able to slightly parkour over small objects. Looking forward to more content being released, maybe a new map as well as new monsters! The different types of objectives are great, but after awhile you begin to memorize the layout and that makes the game a bit less exciting since you know where to expect the enemies to come from and where the items are. Hopefully with more PR as well, this game will become more popular!
Very fun game with variety and leveling. Great stuff!
Great game with amazing graphics and very unique specimens to play against that give it very good replayability.
