I've been trying Ao100 UV for some time, trying different builds. At last I managed to get to a master trait with an Army of the Dead build.
I had to leave the game be at one point, and it looked pretty bleak - the only ammo (besides two rocket boxes I couldn't shoot) was inside my fully loaded tactical and double shotguns. When I loaded the game, the first thing I saw was a sergeant. 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.
Next level gave me the Jackhammer, though I kept it as a backup only, since I still had to save shells. Then a few levels further I entered three consecutive complexes full of formers, and two of them had a megasphere in them. Since shells were dropping everywhere, I could finally let loose with the jackhammer. I wasn't radar shooting anymore, I was radar killing. I could literally shoot anywhere in the dark and the roar of the Jackhammer was always answered by a couple of dying voices.
Then mancubi happened. A couple of levels with bad starting position, some nasty arch-viles and so on, and I finally "rode a mancubi rocket" to oblivion on level 25. 
I think I'll give Ao100 a rest for now. At least I got the bronze badge and hell knight rank out of it.
