Probably close to being the best game in the Twisted Metal series!
PS2 versoin of TM Head On is just awesome. The graphics have had a major upgrade from the PSP version, they look great. As for the sound in the game, it sounds great the cars, missile's, and explosions sound so realistic. It also include's 4 never before seen levels from the never released Twisted Metal Black 2. The game also has a load of cool extra's such as a 30 minute documentary about the past of the TM games. Also a cool little mode called Sweet Tour, to were you run around as Sweet tooth in a asylum finding factoids about the game from the directers themselve's.
Also included in this awesome package are the lost endings from the very first Twisted Metal game, they're very cheesy, lol.
OVERALL: 10/10, a great new TM game for the PS2.
