The Domain of the Undead

The Domain of the Undead is a 1-player arcade game for the 8-bit Atari.

A side-scroller, where the player must combat an endless horde of skeletons, bats, and grasping hands. The player can shoot silver bullets and shoot or move laterally left or right. All shots are blocked by walls, even if these block neither enemy nor player movement. The player can duck to avoid bats, but can not shoot while ducking. The player starts with 5 crucifixes, and loses one each hit. It's game over when all are lost.
