Good point. From RP perspective he got initially captured for having good genes(Robust Genetics, body rejected mutation til this point, also I dont know how mutation paths work and wanted to keep all the options available). After all the experiments and all the talk about untapped potential, he got somewhat curious about mutagens(will start munching on the mutated arms, legs and fetuses after finding a renewable source of water, clearing the lab and making it his HQ).
From metagame perspective I just wanted to minmax stats with maximum available points. Took Robust Genetics to get Quick and Fleet-Footed later or something else interesting.
Really Bad Day challenge as a Tweaker would have given me 2-3 extra points, but its nearly impossible to do, unless you wanted to generate worlds and pray to the RNG gods.
E: Got lucky and found the assault rifle and some military gear. Also NPCs have tried to rob me more than 3 times in the lab(got knife speared, took a full clip of .22 into my leather jacket, got crossbowed, etc) and I am thankful for their contribution in diversifying my diet.
