wait... i have part three. you said it's survival mode. if so, why do you spawn in a safehouse? i recomend that you put these events in a flashing brick to make it so that
onActivate_NAMEDBRICK_(Regular Infected Spawns)_setVehicle_Zombie Standard
onMinigameReset_NAMEDBRICK_(Regular Infected Spawns)_setVehicle_none
anActivate_Minigame_setTimer(or whatever)_BLAH
also make the onActivate event for all the special infected and such.
