EA UFC 3 features tuner sets enabling developers to “hotfix” the game with updates that are smaller than patches. Unfortunately these tuner sets turned out to be defective and were found to crash the game. It is not known why EA failed to detect these crashes and flaws in testing, which Microsoft and Sony require prior to patch releases. Some are speculating that EA implemented “tuner sets” to bypass platform requirements. Many users have reported that EA UFC 3 is plagued with game-breaking bugs and glitches.
