Twisted Metal: Head-On, released on March 24, 2005 (North America) as a launch title for PlayStation Portable, is the first and only Twisted Metal game to be released on PlayStation Portable and is later ported to PlayStation 2. The game is considered to be the "real" Twisted Metal 3, since the game pretends that Twister Metal 3 and Twisted Metal 4 never existed.
At the start of the game, Calypso appears, introduces himself and tells the rules of Twisted Metal. Calypso will grant one wish to whoever wins Twisted Metal.
