Map file used by games developed using the Cube 2 game engine; contains the geometry, spawn points, teleporters, item locations, and other settings for a game map; can be used for storing single or multiplayer maps.

OGZ files are stored in a compressed Gzip (GNU Zip) format. By convention, they are named map.ogz and are stored in a unique map folder within the /packages/base directory of a Cube 2 game installation. They are saved with the files map.cfg, map.js, and optionally entities.json. OGZ files are similar to .MPZ and .BGZ files, which are used by different games that are based on the Cube 2 engine.
