I think they have to bring the original characters back and create a story to sum up how they time traveled. Also add more classified guns and whatnot, m60,stoner63,kiparis, and mac11 (just for shits and giggles). Bigger maps, more open like der riese. New wonder weapon. If there going to bring perks in again, maybe a tactical mask you can buy that protects you from nova zombies. Maybe like the thief round a guy spawns and disables power for time being so its pitch black and he picks a character and stalks them throughout the map and tricks them into splitting up and venturing out.
