Heretic
异教徒
Heretic is a first-person shooter developed by Raven Software and released in 1994. The game transports players into a dark fantasy world where they battle demonic enemies using magical weapons. Built on a modified Doom engine, Heretic replaces sci-fi weapons with fantasy equivalents like the Staff, Crossbow, and Hellstaff. Players navigate through interconnected levels designed with medieval architecture and demonic landscapes. The game features puzzle-solving elements alongside combat, requiring players to find keys and manipulate the environment to progress. Heretic introduces several innovations: a flight spell allowing temporary aerial movement, an inventory system for collecting items, and environmental hazards like lava and poisonous water. The single-player campaign spans multiple episodes with increasing difficulty. Controls use the standard WASD movement with mouse/keyboard aiming typical of early 90s shooters.
