I was playing online a couple of minutes ago on Geonosis. I was almost entirely out of health then I was hit, I believe by a Geonosian's sonic blaster. My health bar then disappeared and though I was hit quite a few times I did not die. It however did not protect me from one hit KOs. I was eventualy hit by a missiel from a Super Battle Droid and died.

somebody said he got infite force 2

Are you playing with a non-PC version? Maybe you accendently turned on, then off a cheat.

I was playing the PC version.

LOL. There's a trainer for Infinite Force/Health, and other such things.
