I already got a S+ on Claire A (normal) and a S for Leon A (normal) and rn I'm trying to get an S+ in hardcore so I can get the rocket launcher. I tried a few times but ran out of bullets a little before completingthe chess puzzle in the sewers

I also run out of inventory slots pretty quickly so if anyone has tips on this I would really appreciate it (ex what I should def take w me and what I can j leave in the item box)

Edit: I know in majority of the boss fights it's better to use knives, but would it be safe to use the infinite knife in case I lose the other ones?
