Rockstar has sent along word that a brand new patch for Grand Theft Auto IV on the PlayStation 3 has gone live, and with it comes trophy support for the game. That's the good news. The bad news is the patch is not retroactive, so you'll need to create a new game to begin earning those covetted trophies in Liberty City.
This patch also helps PS3 owners fight (or become) part of the Zombie Infestation on the online multiplayer and co-op modes.
