Call of Duty: Black Ops 2’s recent PS5 port is reportedly being disrupted by a hacker known as “C isn’t Sharp”, raising fears that multiplayer could become unplayable. Players say the hacker can alter or reset account statistics, grant Master Prestige instantly, and in some cases leave accounts unable to play, making the issue more serious than ordinary cheating.

Streamer Timthetatman was reportedly affected during a match, while social-media posts suggest similar incidents have continued for several days. The concern is heightened because older versions of Black Ops 2 were heavily affected by hacked lobbies, and the PS5 port had recently become PlayStation’s most popular game, ahead of Fortnite and Roblox; Activision had not commented when the article was published.
