Twisted Metal: Head-On Secrets and Glitches (PSP)

Twisted Metal: Head-On is a video game developed by Incognito Entertainment and released by Sony on March 24, 2005 for the Playstation Portable and Christmas 2007 for the PlayStation 2. Head-On shares not only the distinction of being the sixth game released in the Twisted Metal series, but also is the first game in the series to ship fully online-enabled. Head-On is considered a true sequel to Twisted Metal 2. This makes Twisted Metal: Head-On, for all intents and purposes, the "real" Twisted Metal 3 when following the Twisted Metal plot line.

Akin to other games in the series, Head-On revolves around the same theme of a man named Calypso holding a vehicular combat tournament called "Twisted Metal" with the promise of granting the winner whatever they ask for. There is a general "careful what you wish for" theme, as many of the contestants wind up with not-so-happy endings. Amongst the use of regular ammunition, such as bullets, missiles and landmines, vehicles and their operators also have their own special and unique weapon.
