Infinity Ward has issued an patch addressing two guns in Call of Duty: Modern Warfare and Warzone: the AS Val and the SP-R 208.
Both guns, added to the game with the release of season six, had serious issues. In the case of the Val, it suffered from a bug that meant it could shoot through multiple walls. This, obviously, broke the game as it meant players could kill each other from across maps - ignoring cover along the way.
And then the SP-R 208, deemed by most Call of Duty players to be the most dominant weapon in the game this season. This sniper was so powerful, it was felt pretty much essential not just for Warzone, but for Modern Warfare multiplayer, too.
