I feel like I would be rubbish surviving in the Fallout universe. Not you would have to be aware of levels of radiation but also food and water would be tainted with too. That’s not including random mutated creatures and feral ghouls!
I would have to create a base high up so it’s harder for creatures to get me as well as having a bird eye view of any possible dangers. The main aim would be to create a water filtration system and a mini food farm and try and be self efficient as possible and stay out of danger.
