Team Bridge Crossing is a smallish Bagman map made by Stigma.
The two team bases are separated by a river which is spanned by a large bridge.
The bases contain several rooms where there are the usual caches of weapons and items. The team's 'safes' are on the back of the trucks that are located in the two bases.
Don't worry If you end up in the water as there are ladders to get back to the bridge area.
The money drop is in the centre of the bridge along with the only grenade launcher in the map.
Just unzip all files to your Kingpin folder and they will be placed in the correct locations.
It's currently rotating on the Newskool Bagman server.
