After being extremely salty that 1.5 borked my dumb sergal mod, I stopped playing. But eventually, I got an idea- what if I just do the same thing as last time and steal someone else's work?
Thanks to 'Biotech Avali Forked' (sorry I can't find out how to put a link in here, I have done just that.)
These guys will even spawn in your world as ♥♥♥♥♥♥♥ raiders and a real xenotype, so it's nice and self-contained.
(Also since someone asked, you may copy, modify, fork and do whatever the hell you want with this stupid mod- who am I to stifle the creative juices?)
