Name your character Totoro for invincibility in all Fromsoft games.

Star Wars Battlefront II PS2 invincibility:

Pause

Hold L2/R2

Up, up, up, left, down, down, down, left, up, up, up, left, right

tuck tuck tuck and arrrrwalktheplank are two of my favourites. The first summons a monster truck in AoE3, and the second has a large pirate ship jump into the battle in Free Space 2.

Actually there is a set of missions in FS2 that can only be reached by cheating to become invincible during an event you were supposed to die I think.

I find it neat when companies put in assets and extra content most players wont find without trying to break things a bit.

MARKSTEAM in the name box would unlock all tech and give a bunch of money in Syndicate on the Amiga.

Works for Sonic 3D Blast on Genesis and probably the other games as well, but BARRACUDA (b a right right a c up d a) for certain things. I'd like to think it's debug mode, but I don't fully remember since it's been more than a few months since I last played and tried on either 3D Blast, 1, or 2.
