.After that game is almost secured if you reached it with med-packs.
Well, the problem is that I picked Army of the Dead and have only last few shells remaining and no reliable backup weapons. Oh, and two rocket boxes. That's going to be useful without a launcher.
Edit: Woohoo!
After my last post, I decided that I can't wait until tomorrow and that I have to know right now whether I'll die, and it seems RNG loves me. First thing I saw was a sergeant. I killed him with one of my last 7 shells. Next thing I see (and I would never believe I'd be so happy because of it) was an arch-vile! I didn't manage to farm the sergeant much, but in the end I left the level with 2 stacks of shells, newly crafted tactical boots, 150 health, a plasma rifle as a backup weapon (with two batteries!), and invulnerable.
I'll still probably die as soon as that invulnerability wears off, since that's what usually happens when I load a game, but still... this run looks much more promising now.
I never managed to finish an UV Ao100, so wish me luck.
