AI Analysis

The Yard is a single-map Doom II PWAD (MAP02) built as a loose riff on Dead Simple, focusing almost entirely on a pair of cyberdemons as the main encounter. The map is very small and simple in construction, with minimal progression (no keys) and some teleport use to move the action along. Weapons and powerups are extremely generous—multiple BFGs, plasma rifles, rocket launchers, megaspheres, and invulnerability—shifting the challenge toward managing a boss fight rather than surviving attrition. The visuals lean outdoorsy/rocky with grass, stone, and sky textures, and it should run in vanilla-compatible ports.
