It seems someone has slipped up somewhere, Maxconsole has reported that an exploit in the Xbox 360 version of, Call Of Duty: Modern Warfare 2, can unlock those XBLA demos you have downloaded and turn them into the full game, here is what the website had to say.
Oh dear! Certain publishers on XBLA will not be happy. We have it on good authority from L-S that an exploit has been found in Modern Warfare 2 on the Xbox 360 that allows owners to unlock full versions of some XBLA games. The ‘exploit’ works on certain games (especially SNK) including Metal Slug 3, Fatal Fury Special, and Samurai Showdown II. Full details inside. *Update* Multiple users are claiming it really does work and with achievements!
In order to unlock the full versions of these games on XBLA, here’s what you have to do:
- Download the XBLA demo of these games (obviously)
- Launch your MW2 game
- Stay on the main screen (where “press start is present)
- Push “guide” button
- Select “quick start” and select your XBLA gameDone ! There are many games that work with this trick although not all!
Full details will be posted at Logic-Sunrise.com in due course but for now they thought they’d share this with us exclusively!
*Update* L-S claims there is more to it and will reveal more later. However, they are still claiming the above method works
A number of users are claiming it does WORK and even with achievements. Major OOPS for MS!
