This includes two maps for the Sandbox mod, Gazala and City of Pain. It requires Sandbox v0.4 installed.
Gazala is a remake by [BFDS]Alpha from the good old Battlefield 1942, some people even know it from mods like Desert Conflict or Nations at War. Important notice: To be able to play this map you need to have the terrain on your graphics settings at least at medium, otherwise you will get a crash to desktop.
The next map is called City of Pain. It's a dark, snowy city map by HomeGrown. It includes some snow skins and the dirtbike.
