I added my first mod, Cata++ and wow - a whole bunch of new stuff! After skimming through the new scenarios & classes, I rolled & rerolled random chars until I got one of the new ones.
I landed on a Bio-Weapon Alpha character; Kiera “Hunger” Jefferies, who started with XS size. There were a handful of zombies is the lab and an NPC who helped me take them down. After securing the bldg she ate. And ate… then she ate some more. 
Once she cleared out the kitchens of anything edible, she turned to the dead scientists but all those corpses were already rotten. The freshly killed zombies weren’t, however. It’s been two days of gorging herself on zombie fat and flesh and sorting out all the gear strewn about the place. With dulled senses, apparently she doesn’t need anesthetic to install cbm’s so her next task will be to butcher up the dead bio-weapons outside for any salvageable bionics. Until then, she’s gorging herself on tainted fat and meat… Might be miserable for doing so, but at least she’s keeping full and might recover from her starvation soon.
