Shadow Tower

Shadow Tower is first-person dungeon crawler from the team that created the King's Field series. The player controls mercenary Ruus Hardy, who, upon visiting the town of Zeptar, finds it razed to the ground. The towns inhabitants have been killed, and their souls claimed by evil spirits lurking below a nearby tower. This journey will take the player through six "worlds" based on nature, including Earth, Fire, Illusion, and Death, and pit them against monsters and bosses alike. (MobyGames)
