Astrumis – Survive Together, a two-player co-op horror game, now has a free demo on Steam. Explore, survive, and outwit the monster on an abandoned spaceship.
If you’re a fan of co-op horror games like A Way Out or Keep Talking and Nobody Explodes, then Astrumis – Survive Together is about to become your next obsession.
Developed by solo developer Tyci in Unreal Engine 5, Astrumis throws you and a friend into a tense sci-fi nightmare set aboard an abandoned spaceship. One of you becomes the eyes on the inside, the other controls the systems and security cams. Together, your only mission is to survive.
And now you can experience the first 3 levels for free in the official demo, available on Steam starting September 13, 2024.
🚨 What is Astrumis – Survive Together
Astrumis is a two-player online co-op horror game, but with a twist:
One player controls the Survivor, the other becomes Mission Control (the ship).
Your goal is to work together to escape a mysterious spaceship haunted by an invisible monster. Only the Mission Control player can track the creature’s movement via security cameras. The Survivor, alone in the ship’s corridors, must rely on those instructions to stay alive.
