Nightmare of Decay

After going to bed, you awaken trapped in a multi-level manor overrun by zombies, armed cultists, and other horrors. Your goal is to find a way out.

Explore rooms and corridors, collect keys and useful items, and solve puzzles to open doors and reach new areas. The manor’s connected layout makes finding routes and unlocking sections part of your progress.

Fight varied enemies with an assortment of weapons while managing limited ammunition and healing supplies. After the campaign, additional activities include wave-based survival, randomized dungeon floors, and a campaign with rearranged enemies and items.

Players frequently enjoy the game’s old-school survival-horror approach, retro presentation, and tense manor atmosphere. Reviews also praise the puzzle-led exploration, resource-conscious combat, and extra modes that offer more to play after the short campaign. Some players find the controls and movement deliberately slow, and several wish the campaign were longer.
