Mummy: The Resurrection
A roleplaying game from the Old World of Darkness. As the name suggests, you play as a mummy, which in this case means someone given immortality by the Spell of Life. You can still get killed like normal, but you'll always rise again from the Underworld unless they use a nuke (at which point you'll get stuck in the Underworld as an indestructible ghost).
Its New World of Darkness counterpart is Mummy: The Curse.
