What is Astrumis - Survive Together like?
An exclusively co-op horror game for two. One of you is a survivor walking an abandoned spaceship and the other controls the ship, using its security cameras to find an invisible monster.
The survivor cannot see the monster, but the player on the ship can through the cameras, so one of you gives directions while the other moves. You also solve cooperative minigames that neither player can finish alone.

Will your group like it?
Pairs who like horror built around talking to each other, in the vein of A Way Out and Keep Talking and Nobody Explodes.
