I sided with New Life second, I sided with Bio-Tech and then preloaded the save to see how it was siding with New Life. New Life gives you 2 mil for helping them, Bio-Tech gives you 1 mil. Though the crew do react a lot better when you side with Bio-Tech, and there’s less fall out if you side with Bio-Tech
If you like Garth? Then I’d suggest siding with Bio-Tech. Spoilers!
Garth doesn’t make it if you side with New Life, you basically kill him and majority of his kind if you side with New Life. Honestly other than the money, Bio-Tech seems the more moral choice
