A hotfix was released today to fix a glitch which allowed players to increase the damage of their weapons via a proficiency. The glitch is similar to the Stopping Power perk in Call of Duty: 4. Either way it is not allowed in Modern Warfare 3 as it makes players overpowered and the game unfair.
Users had been complaining about this problem for a while so we are glad it has finally been fixed.
The update has been applied via a hotfix so it will install and fix the problem all behind the scenes without you knowing.
The hotfix was revealed in a tweet from Robert Bowling: “Released a hotfix for Modern Warfare 3 which prevents users from exploiting the ‘Damage Proficiency’ glitch. Have fun, play fair!”
