can anyone offer me some tips on how to beat the last friggin' censor? I keep dying and can't get away to complete the task....no matter how fast I try to run/jump/shoot, I end up squished.

Okay, so first of all, have you run around the whole cube psi blasting the...valve thingies? You do this so the big censor can't re-genrate. Once it's done, hit the targeting button and whilst you're focused on the big censor, jump left or right, you'll still be facing and you'll be doing sort of side flips so you can dodge the sensor when it come at you, then just shoot at it al the time to kill it.
