If you mean making your own map, it's Forge mode.
use the stick!
The maps themselves are preset, but you can choose what is in it from guns to scenery to vehicles, using the forge.
If you are playing in edit mode click on the y button then click on weapons then look for it. If you are not then you will jsut have to find one.
