I was thinking about the fusion of Hightower and 2fort. It can be pl map or "plrctf" map (fusion of payload race and catch the flag). You will have to capture 2 flags to activate payload race. No matter who will cap 2 flags payload will unlock and who will take it to the end first, they will win. Its like cp_dustbowl that has 3 steps to win. There it has 2 steps to win.
