Inspired by the America's Army map titled "Bridge Crossing", this is a 3v3 blood game similar to Beach Blood, Hit & Run, etc. involving only automatically spawning ranged infantry which upgrades after getting kills.

Unrelated: I really don't know what Sniper IX liked so much about Bridge Crossing. When I played it with him he sucked at it and I thought the map sucked in general. It was just grenade spamming and camping...
