Map file created for games that use the first-person shooter game engine "CUBE;" stores the layout and objects included in the level; used for both preinstalled maps and custom user-defined maps. The CUBE engine was used for creating the games Cube and AssaultCube (formerly ActionCube). The engine was refactored into another game called Cube 2: Sauerbraten, which stores maps using .OGZ files. NOTE: CGZ files for AssaultCube should be stored in the following directory: /assaultcube/packages/maps/.
