Assassin's Creed patch now out
The patch is now live and should update as soon as you launch the game on your PS3.
The official word came from Ubisoft over the weekend:
Following consumer feedback regarding some issues while playing Assassin’s Creed for PlayStation 3, a corrective update has been developed and will be released worldwide on the PLAYSTATION Network over the next few days. You can proceed to installation simply by launching your Assassin’s Creed game. Please note that release times of this update may vary depending on your location. Thank you again for your patience.
I have it on good authority that the patch is live across the UK and Europe right now so go ahead and update your copy today.
