Vanish

Vanish starts with the player being dragged down an underground corridor and thrown into some sort of cell. As the sturdy metal door slams shut behind the game starts for the player. Opposite the sturdy metal door is a grate that has a large enough hole in it so that the protagonist can enter the labyrinth on the other side. The player must now help the character escape from the underground labyrinth. Notes on the walls can be found here and there and they might help with the escape. But the character must be careful because there are other things moving around in the darkness.
