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

it good game
Extremely fun in team even if it's the same map for now, a new one is coming soon enough, it's really alien isolation but also you have 3 buddies and here's some guns, maybe those will help, good luck! Also you can blow up the ship whenever if you feel like it
Love this game. Much death, lots of discovery.
I love this game. I've waited for a horror CO-OP since Dead Space 3, the Sci-Fi is astonishing in this game. Even with strangers, a buddy to play with, or going solo, this game delivers! The graphics being optimized seriously kept me immersed, beautiful lighting!
Think of Alien Isolation but multi player and more aliens! Fantastic game! Cant wait to see the next map and more species. Highly recommend this game for any space and alien lover out there!
Beyond boring enemies.
arguably one of the most fun coop games ive played in awhile. graphics are stunning, gameplay is fun, the random monsters are terrifying. i hate that its still Early Access, and wish there were more maps, and a few other gamemodes. But being that its EA it feels incredibly polished and well built. 9/10 recommend.
absolute peak of a game 🤌🤌✨ Can't wait for the future of it, as well as further updates and features to release!
