ok so on timesplitters 2 they have a gametype where you invade the enemy teams base by doing several objectives like defusing cameras and turrets to blowing up generators. i think this kind of idea would be great in the halo sandbox kinda like firefight against the covenant or maybe against the other team. ok hear me out, the objectives could be enable the switch to break in first like the swithes on most maps then there could be an armoury or bunch of vehicles or supplies that have to be destroyed then youve got to destroy an outpost or generator or something then maybe destroy a base radio station that enabled the enemy to respawn or sent more covenant into battle then wipe out all the remainder enemies, if this is against the covenant it would be sweet destroying a half built scarab or weapon making facility and not have it be a strict campaign mission so these kind of objectives could be created in forge aswell
