Ack. That could have gone much better. I forgot to note when I entered UT3 as well. However, here's my first attempt.
52 carnivorous plants
72 greater carnivorous plants
23 giant carnivorous plants
Total: 147
Noteworthy stuff:
4 cans of healing fluid
2 bottles of troll blood
Wand of teleport
Bronze short sword +1
Iron short sword
Iron chainmail
Troll hide cloak of fire resistance
Gauntlets of Dexterity +2
Oh yeah, almost caught leprosy on UT2. Ran away and later found out the zombie spoiled away
Also, backpack. I planned to go out with a bang should I find myself surrounded and near death, but I was fighting a pair of giant carnivorous plants, I killed one, then the other one got a lucky shot on me, ending my killing spree.
Also, I don't think you should judge survivor category by turns. Healing over 15 minutes counts as a single turn, as does searching in 5 seconds.
