Classmaster

Classmaster is a co-op game mode for 1-4 players in Zombies created by RisingSun2013. It draws inspiration from Sharpshooter from multiplayer in Call of Duty: Black Ops and Call of Duty: Black Ops II but is very different.

Summary
Players start out with totally randomized loadouts using stuff in the map: random weapons (including the possiblity of a Pack-a-Punched weapon), random equipment, random Perk-a-Colas, a random GobbleGum, etc. It's even possible to only get one gun, though the player can only get up to two unless they are given something which allows them to have more or the map allows for a greater amount by default. Players are also given infinite ammo (with default rules) for all weapons and equipment in their inventory. Every round the player survives, the loadout is randomized again in the same way it is at the start of the match. Every player gets a different loadout when the loadout is randomized, even at the start of the match (although there is a very rare possibility of ending up with the same loadout).

Power-ups are still dropped and can still be acquired in this mode. Also, all doors are opened up in this and there is nothing to buy. Zombies are harder from the start as well, health-wise. Overall, it is basically a heavily-modified version of Survival.
