The player controls a baseball superhero named Batsu (Bats) who must use baseballs to defeat his opponents. Being hit once reverts him to "normal" Terii (Terry), who swats at his opponents using a baseball bat. Opponents include machinery, humanoids, and animals. Killing opponents while in Terii form results in a larger energy bar.
