A glitch has recently been discovered in Modern Warfare 2 which is frustrating for Xbox Live Arcade developers, this is because it unlocks content, which gamers should have to pay for.
The glitch can accidently unlock full versions of five SNK Playmore games on Xbox Live Arcade, these games are as follows Garou Mark of the Wolves, King of Fighters ’98 Ultimate Match, Metal Slug 3, Metal Slug XX and Samurai Shodown II.
To work you must have the demo of the game you want to unlock installed, then simply launch the demo whilst Call of Duty: Modern Warfare 2 is loaded, this will start the full game, if however you start any of the games from the usual dashboard only the demo will launch
It is almost certain that the bug will be patched up soon. If you have been lucky enough to have had this happen to you we would like to hear from you.
