This map takes place in 3 large cylinders. Originally, each team started off in the two farthest cylinders and so did the flag, and they were forced to go through tiny pipes. However, this was a great failure, so I moved the flags to the center of the map. Each team also has two smaller cylinders which can make for excellent bunkers as each has its own set of ammo crates.
