Killing The Big Blue Stadium Music

During story mode, go up to the stage where the band is performing and blow them up ( The napom beside them works perfectly ). The moment they are killed, the song will stop playing and will be replaced with a different, lyricless song.

Glitches

Playing multiplayer with one game

If you want to play Twisted Metal: Head On with other PSP players around you but only have one copy of Twisted Metal, here's how you can do it:

1.Load up Twisted Metal on PSP number 1.
2.Create a game on Ad Hoc mode and start the game.
3.After the game loads, take out disk.
4.Put game in another PSP and load up game and join the multiplayer game that's been created and Join in and load up the game.

Now you both will be able to play the game in multiplayer mode. This trick can work for more than two players but the max number of players possible is 6.

Destroying the Tokyo Tower and entering the dojo

In the Tokyo Streets level, goto the big red Tokyo Tower. Use a remote control bomb on the side of the tower. It'll blow up the tower. Blowing up the tower will leave a bridge, connecting to the dojo (behind the teleporter on ground level). At the dojo is health and other weapons.
