Ya know as much as it prob won't happen, you could be on to something. Everybody got in a tizzy about John Bernthal "Shane" from TWD being a character in AW Exo zombies it got the hype up and people just loved that a zombie guy was in a zombie game. Its possible we will see other TWD actors in zombies. Don't forget Micheal Rooker too.

With that being said, you can still grab ammo off the wall with the same gun even if there are different attachments on it. Proved very useful when I got the Ak74-u w/ Extended Mag. If you dig up an mp40 tho it doesn't fill ammo it replaces it with a normal one. Another tip is that if the robot steps on the soul chest it starts over so it's best to train them with one massive horde.

The ultimate staffs are one hit melee till round 19. I ussually have the ice staff ultimate by 12 or higher. Include an insta kill in there and I got strike bombs by at least 15. Might not be the earliest option, but doable.
