If you're still having fun roaming the Wild West in Red Dead Redemption, you'll be pleased to know that Rockstar has issued a patch for the game to make things run that little bit more smoothly.Bug fixes have been made for the original game, as well as the DLC packs
Liars and Cheats and
Undead Nightmare (both the disc-based and download versions of the latter). Chief of the changes include re-enabling world-wide multiplayer compatibility in Japan, fixing stuck player instances and recognising zombies as enemies for particular achievements.
You can download the patch for either the Xbox 360 or PlayStation 3 version now. Read the full patchlist
