Main focus of Eraser is survival horror gameplay and exploration — setting the player loose with low health and almost no ammo, through a massive artificial hellscape inspired by the likes of: Blame!'s megastructure, Control's oldest house and M.C. Escher's drawings. Things eventually escalate into more familiar Doom-style combat.

Includes a custom arsenal, custom monsters and ambient sounds. Has two endings, with the true ending requiring 3 secrets to be accessed. Expected playtime is upwards of an hour for first runs, but could be maxed approximately in 55 minutes if you're familiar with it.
