There’s a famine and feast in my playthrough. I’m very conservative with ammo but my partner was interested in playing and uses much more resources. Getting lucky in fights like getting a leg shot to drop them to the knees in a couple shots and melee them off has really saved me on both ammo and healing. I just got to the historic society and you feast on the way there(I missed the elevator challenge box which gives quite a heafty prize 😭.)

I haven’t saved so much than back in like ps1 days 😭. I’ll clear out a handful of enemies and back track to save. Literally got my ass handed to me at full health by a singular nurse with me fully loaded on all ammo.

I’ll give you a tip tho that took me a bit to force myself into, it’s much easier to shoot their legs bring them to their knees and then hit them with melee. I tried to be all melee to conserve ammo but each engagement just cost way too much in health items. If you can spot them while they are standing still and get a couple leg shots you’ll end the encounter quickly and safe.
