First Room is the purest discipline in COD Zombies: no Pack-a-Punch, no easter egg, no train around the map. You hold the starting room, you keep the doors closed, and you push the round counter as far as the zombies allow. Every high round, world record and personal best on this page is backed by its video and checked against Call of Duty: Black Ops, Black Ops II and Black Ops III.
