(adsbygoogle = window.adsbygoogle || []).push({}); some of you might know, but for the others, this is how you do it.

1. critical mass upgrade, buy it.
2. adrinalen surge, buy it.
3. go to a war/fighting event. (without a vehicle)
4. let the enemies cripple you till your health is only flashing blue.
5. press START. go to QUIT. RESTART EVENT. and RESTART EVENT, again.

test it out by letting enemies damage you, if it doesnt work try it again, never took me more than twice.

**NOTE: you have to complete the event your doing this on,AND.....btw this is a BIG "and".....if you FAIL a mission, it will reset and you'll have to go to an event again to turn it on.

**SECOND NOTE** i didn't discover this...but its ours for the taking..

if anyone has a save at the beginning of the last mission on hard and can share it I would love them forever.

once you unlock this invincibility, does it stay working throughout the entire story? If so, why don't someone unlock the invincibility, and 2 or 3 others invest some time in playing the game till the tank mission, and then upload the save here? Because playing invincible will be a breeze anyway... so it shouldn't take that long to reach the tank mission anyway...
