I was lucky to find a nuke, which made the standard win possible. Didn't find invulnerability.
I was lucky to find an assault shotgun as well as a power mod shortly after. A power modded red armor helped me get through a tough spot near the end (although it didn't survive). I spent time getting the BFG in case I had to go on to attempt the full win. It probably would have been about 40-60 seconds shorter otherwise.
I can still feel my fingers mashing rfrfrfrfrf
Edit: Oh yeah, Ironman. I blame that on button mashing; I meant to do dodgemaster.
