Vaporum

Vaporum is a grid-based, single-player, first-person dungeon crawler game in an original steampunk setting inspired by old-school games like Dungeon Master I and II, the Eye of the Beholder series, and the more recent Legend of Grimrock I and II. Each enemy type in Vaporum has its own strengths, weaknesses and attack and defense mechanisms, so you'll have to use different tactics to defeat them. Choose your equipment wisely. Weapons differ not only in their damage levels and appearance, but also in their unique bonuses or behaviors.
