Arena MatchDescription
With Arena Match you can create arena mutators for (almost) any weapon you like. The weapon can be selected from a menu or you can select several weapons and let the Arena Match mutator choose one of them each time a new map starts.
Arena Match allows you to keep the default weapon (usually the Impact Hammer or the Chainsaw) and the Translocator. You can also configure it to work only as a default weapon mutator (like Chainsaw melee).
In addition to the configurable Arena mutator you get another mutator that can change aspects of gameplay like the damage every player does or how fast players can move.
