A compilation including enhanced versions of Power Stone and Power Stone 2, two classic 3D Capcom fighters. These fast and furious 3D brawlers put a new spin on "last man standing" as characters take each other on in frenzied match ups amidst fully interactive environments. Fighters vie to collect Power Stone gems in order to tip the scales in their favor, as nabbing three will allow them to transform into super fighters that can perform devastating power moves. In addition, a variety of zany weapons and the ability to use environments in creative ways allow an incredible level of freedom and depth beyond the typical fighting game. Multiplayer support via the PSP system's ad-hoc mode raises the stakes as friends duke it out in frenzied no holds barred battles with Game Sharing for up to four players. The PSP Power Stone Collection also bonuses such as the Bomber Battle minigame, visual layout fixes, extra characters in Power Stone 1, and new unlockables.
