On March 4th, somebody discovered that the forthcoming DLC characters for Street Fighter X Tekken were already on the retail disc. Since then, hackers have been 'unlocking' these characters for use in their games. Not only is this stealing since Capcom is selling the additional characters, but it's also plain cheating since the characters aren't even out yet. These unlocked characters have even been making the rounds on Xbox Live, as numerous gamers have reported. Capcom has addressed this issue and detailed its plans to take action against it. 

Initially, Capcom had arranged for players who capture "screens or video" of a hacker using these characters to add the evidence to a thread. Later this thread was closed and Capcom promised to capture the hackers single-handedly. Currently, convicted hackers (and the consoles affiliated) are being banned from Xbox Live. I play this game online regularly on the PS3 and I haven't seen any of the DLC characters yet. I wonder if and when hackers will get around to it...

Street Fighter X Tekken is available now.
