Mayhem 1500 is a 2016 community-created modification (Mod) built for Doom II: Hell on Earth, requiring a Boom-compatible source port on PC. As a map pack, its core gameplay loop involves intense, fast-paced shooter combat across newly designed levels. Its distinctive feature is a structural constraint: every map adheres to a strict maximum of 1500 linedefs, forcing designers to create dense, efficient combat arenas based on the classic FPS mechanics.
The core experience centers entirely on level design and combat encounters, staying true to the fast-paced, arena-style shooting mechanics of its parent game. Since this is a map pack, the focus is on presenting players with entirely new environments and challenges crafted by various contributors rather than introducing new narrative elements or character progression systems.
The primary value proposition for players lies in experiencing fresh, custom-built levels that test their mastery of the original game's mechanics against new enemy placements and architectural layouts.
This specific iteration of the annual mapping event introduced a strict structural limitation for its creators: every map included had to adhere to a maximum budget of 1500 linedefs. Linedefs are fundamental building blocks used in the map editor to define walls, sectors, and geometry within the game world. This constraint forces designers to be highly efficient and creative with their spatial arrangements, often resulting in maps that are dense, intricate, or focused on specific types of combat scenarios within a limited structural footprint.
This release is a standalone modification package. There are currently no officially listed downloadable content packs, expansions, remakes, or remasters associated with this specific project. Its current state reflects the culmination of the 2015 mapping event, providing a fixed set of custom challenges.
This content is available for play on PC running Microsoft Windows. Due to its nature as a modification for a decades-old title, players will require a compatible source port—specifically one that supports Boom functionality—to load and play these custom levels effectively. The genre classification remains firmly within the realm of classic First-Person Shooter.
