According to the ESRB, XSEED Games will be publishing Valhalla Knights 2: Battle Stance for the PlayStation Portable. This game is a retooling of Valhalla Knights 2 and changes some aspects of the battle system. The party size is dropped from six to four to mitigate slowdown that occurred during combat. Party member and enemy AI has been tweaked to accommodate the drop in allies. The Nameless Tower is now fifty floors instead of ten, and new quests and additional teleport points have been added as well.
While we still have yet to see XSEED's official press release, these are the changes found in the Japanese version. There is also no word on whether this is a UMD release, a PSN release, or both. As soon as we have details from XSEED, we will let you know.
