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:
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:
Ranked by shared tags, then by score.
Lethal Company
You are a contracted worker for the Company. Your job is to collect scrap from abandoned, industrialized moons to meet the Company's profit quota. You can use the cash you earn to travel to new moons with higher risks and rewards--or you can buy fancy suits and decorations for your ship. Experience nature, scanning any creature you find to add them to your bestiary. Explore the wondrous out
Escape the Backrooms
Explore the seemingly infinite expanse of eerily familiar levels in backrooms based on the popular creepypasta lore. Each level features different ways to escape with dangers along the way. Realistic graphics, minimal user interfaces, and dreary ambience combine for an atmospheric horror experience that's terrified millions of players on Steam. Explore the backrooms
