In case you've been noticing a lot of what seems to be wallhacking going on in Call of Duty: Modern Warfare 2, it's probably been the cause of a bug rather than actual cheats - players discovered an exploit allowing them to use the game's own pinging system to their advantage. The developers opted to disable pings entirely for the time being.
In the wake of Activision's swift response to what was a rather major flaw in the newly launched Modern Warfare 2, fans are now wondering when the key gameplay system will be reinstated in a fixed state. Ever since pinging mechanics were popularized in team-based shooters by the Battle Royale genre, they've become a staple, and its absence is impacting the experience for many.
The reason why Infinity Ward had to step in and gut the feature entirely was due to a bug that allowed players to co-opt is as essentially a "wallhack". Pings allow teams to easily communicate by marking and highlighting objects, weapons, locations or other players on their screens, which seems like a simple enough mechanic.
