It appears that Twisted Metal’s online multiplayer mode is unplayable for those outside of the US.
The problem was first reported last Thursday by members of the PlayStation forums, though Sony have yet to officially release a statement regarding the situation. David Jaffe, Twisted Metal’s designer, took to Twitter apologising.
“I am hearing this and sorry about it. I will know what is up on Monday. No clue why SCEE territories are locked out :(.I’m sorry.”
So, it looks like we’ll have to wait until later today to get a clear answer as to why gamers outside the US have lost access. If you want to play the single player it is advised you sign out of PSN.
