Tatsunoko vs Capcom: Ultimate All-Stars. It's very similar to the Japanese box art for the original release, in that it's a bunch of the game's characters set against a white background. The difference between the two is that our localized version shows the characters staring each other down, likely thinking about how they're going to kick the crap out of each other. What a violent world these folks live in, eh?
Head past the break for the full box art.
