0.C-3391. I really need to update by the way. Also, after doing some testing it appears I am mistaken. Loose ammo won’t get you through a metal lab door (neither will dynamite, but that’s another matter). I might be misremembering time playing pre-0.C or it might not even be possible in the first place.
I’ve got 40 Strength (18 Alpha Base + 2 Bionic Strength Enhancer + 20 Hydraulic Muscles) and can’t batter down either the new lab doors or concrete walls in the experimentals. Pickaxe, either Jackhammer, Acetylene Torch, Mininuke and Motor Vehicle are some of the only ways to get in without an ID or hacking.
