When I found a Science Lab and a Science keycard for the first time, went in with a shopping cart, and filled it -entirely with purifiers and serums-.
Unfortunately, I was rping a southern belle character (custom profession I made on my home copy, including an encumbrance 5 poofy dress) whom wouldn’t use them if her life depended on it, so that vast, vast, vast amount of Wonderful Mutant Fun ™ is going to go to waste.
The most useful lucky moment was when I found a flashbang grenade like a minute before I encountered a T-Rex. It ate one of my followers, I threw a grenade at it, and raaaaaaaaaaaaaaaaaaaaaaaan.
