Reads the release: "As in the single player mode, you'll want to land punches at the right moment to build up Star Punch points that translate into almighty haymakers! Landing and dodging blows in Head-to-Head mode also builds up a Giga Mac gauge. Once full, your fighter is ready to inflict some serious damage."
Nintendo also notes that characters Von Kaiser, King Hippo, Don Flamenco and trainer Doc Louis all return.
Punch-Out!! arrives May 18 on Wii.
