I dont think adding a double barrel shotgun (its benefit could make it easier to kill a bear?) and some sort of pistol is to much fire power, i wouldn't see the need for a rocket or a nuke haha. And the fact that you have to search for limited ammo/weapons makes it a survival game anyways. More variety of craft-able weapons such as sling-shot/spear makes sense as well. All of which have been mentioned in previous posts.

Adding more dangerous wild life such as a cougar/lynx/bobcat while in the mountains would add a challenging twist. Adding a shotgun/revolver and (ammo boxes/shells) to the map(s) would add more variety for defense. I think that it would be neat to harvest deer antlers with the hack saw specifically (some deers can have them while others may not?), it could be useful to craft a sling shot like many have asked about, rocks/pebbles could appear for collecting as ammo. I just wonder if the game could work as co-op (2/4 players?).
