CoD Zombies: Alpha Omega (BO4)

After retrieving Ultimus from Groom Lake, both them and Primis travel to Nuketown to find the Elemental Shard for the Agarthan Device to destroy all universes. The map itself is another expansion of Nuketown Zombies, this time adding the area before the Cul-De-Sac and a Bunker. The Galvaknuckles make a return, and so does the Avogadro as a boss. Four new types of zombies were added as well: Nova 6 Bombers, Jolting Jacks, Lightning Hounds, and Nova 6 Zombies. The Ray Gun MK.II returns, this time boasting four elemental upgrade quests.
