I'd like to see a better use for these hotheads, my first thought was to tame and milk their explosive fluids to use in bomb and shell crafting.
Maybe ad a small chance for the colonist to combust when doing the milking?
Chemicals and Neutroamine (https://ludeon.com/forums/index.php?topic=26108.0) lets you drain Neutroglycerin from Boomalopes/-rats, which can be refined into Neutroamine. There's no chance of setting pawns afire, but population control proves to be difficulty.
I like this mod a lot, but my desire goes a bit more into the direction of "volatile chemicals" of Boomalopes/-rats. You might want to check it out anyway.
At least that'll make boomalopes worth taming
Seconding Chemicals and Neutroamine Crafting. Absolutely excellent mod; ought to be part of vanilla. I made a mod just for my own use that replaces various recipes bizarre ingredients (eg: Kevlar helmet) to use Neutroglycerine instead.
Personnally, I always tame some boomrats and learn them release.
i just keep some couples for the reproduction, which is very fast, they are rats.
When some of them explode in a middle of a pack of tribemen, they put them on fire and after it's pigeon shooting.
Harvesting chemfuel will already be worth it to have a pack of boomalopes. Now, chemfuel is of little use but later on it'll supposed be have more use.
Chemfuel would be great for a kind of chemfuel generator. Milking Boomalopes and Boomrats for chemfuel and using that to power your base would be great and would give them some purpose outside of suicide bombers.
