AI Analysis

A single small DOOM II map built in a compact tech/industrial style, dominated by METAL2 and brick/pipe textures with a bit of water and sky. There are no monsters at any difficulty, making it effectively a sandbox or weapon showcase rather than a combat level. Despite the tiny scale, it places a full high-tier arsenal including BFG, plasma rifle, and multiple super shotguns and launchers. Progression is straightforward with no keys, teleports, or secret exit, and it should run in vanilla-compatible ports.
