LOL, I managed to totally trash my suit during this mission where you wreck the construction site and try to mop up all the guards.
For some reason I didn't manage to kill all the guards, so I activated the shield ASF (this piece of equipment is godlike - after the whole ordeal I was at 59% health and I wasn't even wearing heavy suit, just medium - I suppose they had to cut me out of it later) and rushed the overwhelming enemy forces concentrations the survivors might have reached effectively single handed, because it took my squadmates time to reach the fray, and by this time, only few enemy drones and, I think, one ground based target remained operational.
Result? I've managed to royally mess up my suit - everything, every fucking system, save for power plant and weaponry (still, the rocket launcher got slightly battered), was at 0%. Good thing I managed to fire off all my missiles before the targeting systems gave off their last breath, as afterwards I was running around effectively blind (the display glitching up all the time so much that it wasn't even funny), unable to target anything, unable to get the ID-lock on anything, with sensors gagging and puking up splotches of rainbow-coloured dots, relying solely on my FPS skills to rake anything around that didn't look like tree or fellow SFC member, but either moved or looked man-made with ion beam.
Good fun!
:D
