AI Analysis

SUBTERRA is a single-level WAD replacing MAP01 for DOOM2, designed for single player and multiplayer modes including co-op and deathmatch. The map features a medium-scale layout with 181 sectors and over 1000 linedefs, emphasizing a techbase and industrial theme with heavy use of metal and support textures. Combat includes a moderate monster count with a mix of hitscanners and projectile enemies, notably many imps and revenants, but no bosses. Resources are balanced with a variety of ammo types, armor, and health pickups, supporting sustained combat. The progression is linear and straightforward, compatible with vanilla DOOM2 engines without new graphics or sounds.
