Affecting both the downloadable demo as well as the full version game, the Modern Warfare 2 glitch grants players access to the full versions of five different SNK Xbox Live Arcade games.With Modern Warfare 2, the glitch forces the trial version XBLA games into thinking that they are authorized to run as the full version. As a result, they launch into the complete, unrestricted game, even if you have not yet purchased them. Oddly enough the glitch only seems to effect the combination of Modern Warfare 2 and the SNK developed XBLA games. Other titles tested behaved as expected.In order to see the glitch in action, you only need to launch Modern Warfare 2. Once the game and/or demo has booted, press the Xbox 360 guide button and select "Quick Launch." Now, highlight the XBLA SNK demo that you want to play and confirm the selection. The XBLA game will launch as a full version.The SNK games affected by the glitch are: Garou: Mark of the Wolves, The King of Fighters '98 Ultimate Match, Metal Slug 3, Metal Slug XX and Samurai Showdown II. Fatal Fury Special and NeoGeo Battle Coliseum are unaffected.
