Warehouse is the dev_warehouse map released by Dev04 on the Cfx forum. The original release links to the same Cfx-hosted ZIP previously listed here, so the archive can now be traced to its release thread. Dev04 describes a two-room interior with three entrances at 898.1000, -1033.4728, 34.9669.
Download through the original release below. Place dev_warehouse in the test server resources directory and add start dev_warehouse to server.cfg, as instructed by the creator. Visit the coordinates and check entrances, collisions and overlap with other maps before using it on a live server. This review verified the source link and archive identity, not in-game performance.
