All you have to do is take any weapon, say the carbine, and switch the projectile with the wraith mortar, or any other explosive projectile.
then you go to the projectile tag and change the damage to 0 and the force to 999999.
then just resign and ftp.

this makes it so that all of the boxes ,or anything else that is lagging the game, get forced out of the map and it speeds the game up incredibly
