Shoot the other helicopter! or else…
DO NOT use performance mod! this will break the map! Map modification was made by me, Magica, Helicopter script was made by an awesome guy named SnakeyWakey and the original map was made by Kosi34 on Youtube. Uses many vehicles by other developers.
Also there are Controllable helicopters on the map!
I recommend using EasyCleaner to clean debris for less lag.
