Actually TPM does NOT have an invulnerability cheat. If you want to be invulnerable, you need to download a 'trainer' which a program you run in the background that let's you have 999 life all the time. Check out jediknight.net's TPM section I'm pretty sure it's there for u to d/l. If not do a search for The Phantom Menace cheats or trainer.
It's not the kill
It's the thrill of the chase
