Activision and Red Octane rolled out an update for the Xbox 360 version of Guitar Hero II this weekend, and already a mass of unfortunate downloaders are reporting 'bricked' Xbox 360s caused by the update.
The patch was released to address a whammy bar response issue, but if the mass of internet postings are to be believed many people are experiencing game freezes or even the infamous 'red circle of death' leaving them with a botched 360.
Of course nobody has provided anything in the way of actual proof yet, but considering the outpour of reports it's likely that the whammy bar update is causing problems for some users.
As usual once they're in the office we'll get on the blower and let you know what Activision have to say on the matter, but for now - download with caution.
