There are so many COD zombies players and I know for a fact that every fan is itching for Treyarch to come out with an all Zombies game that includes every single map digitally remastered for the PS4 and XB1.  It would be great to even have the XP-progression system that was introduced in Black Ops 3 zombies.  I would definitely buy a copy, whether it was on disc or digital-only.  Please make it happen.  For any fans that want this to come true, please sign the petition.
