The latest look at Call of Duty: Black Ops 6's Zombies mode appears to confirm the return of the PP90M1. This fan-favorite gun was incredibly popular following its debut in the original Modern Warfare 3 from 2011, and was used due to its rapid rate of fire and small profile. Treyarch teased the weapon in a new intel drop for Black Ops 6 as the game's release date steadily approaches.
