Now that the
FireMod add-on is released, I think a firefighting gamemode should be made.
There would be 2 teams: Firefighters and Vandals.
Firefighters have to stop the fires started by the vandals. They win if they successfully manage to stop too much damage from being caused by the time the timer runs out.
Vandals have to cause as much destruction as possible by setting buildings on fire. They win if they successfully manage to destroy several buildings in the map before the time runs out.
