GTA IV locks up on both formats, says internet
According to a slew of reports in the past couple of hours, gamers are complaining that a small percentage of both PS3 and 360 version of GTA IV have been locking up after the intro sequence. Rockstar is yet to respond and we haven't seen any proof as yet, but expect more on this before the end of the day.
Update: Sounds as though it's happening to both versions. We'll have more on this later.
