And if that's not enough, the arcade mode is the most efficient way of earning the currency needed to purchase extra colors and other bells 'n' whistles in the game's shop. It's presumably not the only way, though; TvC includes a top-down mini-game called Ultimate All-Shooter. I'm told it's a lot of fun, but I wouldn't know: The requirements to unlock it (i.e. perfect play in a throwaway mini-game only accessible during the arcade mode's end credits) have managed to roadblock me for 48 straight clears. Good thing I've already unlocked every last item in the shop, and even better that I've come to the conclusion that none of that stuff matters anyway, Capcom.
