The game uses a first-person perspective, very similar to first person shooter games, only without any means of combat. Throughout the game, players must travel through different areas of The Mesh and beyond, and must solve puzzles to progress to the surface. The player encounters only one type of enemy, and that is the mutating monster. The only possible way for players to survive is to run away. Any close contact with the enemy will result in the deaths of their companions (and finally themselves). Once the companions are attacked, they are killed off permanently.
