Border Patrol
Two teams, Mexican and Americans (Or Canadians and Americans, or whatever you want really, maybe even Robloxians and Blockheads)
The Americans have a sort of gate with towers, and down below there is a dark tunnel under it. If any of the Mexicans touch that tunnel, the game resets. The Mexicans have just a pistol, and the Americans have rifle, and a pistol.
Make it sort of like a long tunnel, like Runner's VS. Snipers.
