Perfect Harmony fills in that multiplayer hole Capcom has yet to rectify. Gameplay is incredibly authentic, dense, and just plain fun. Best of all? It works. By all means, don't take my word for it. Try it out yourself! You can download the playable demo at the Rocks Clan. There you'll also find full instructions on installation.
As per usual, just about everything you see could change before the game's release. But so far, the game's pretty solid as is. We'll keep you posted when the full game hits!
