Today Atlus released a new patch for Persona 4 Arena that fixes up the game’s balance a little bit as well as some network problems that were still plaguing the title. It is also worth noting that this patch fixes the bug that was preventing players from unlocking the “Network mode Level 30” trophy or achievement.
The patch will be available to download as soon as you start your game, and is mandatory unless you don’t feel like playing online with the game at all… which sort of defeats the purpose of the patch in the first place. As for those of you in Europe still waiting for the title… at least when it hits your region most sections of the game will be fixed and 100%!
