dCoolldoown plays cooperative First Room: 4 team runs at four players, alongside edguy9187, ThePrettyRabbit and SzilooHU. Team runs are listed for the record but score no ranking points, as no difficulty coefficient exists beyond two players.

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 Black Ops 4. Follow dCoolldoown on the ZFRR leaderboards to see their next run.
