1. Firearms
NOTE:

When I say firearms, I DO NOT mean these:

This is what I mean:

They would be made with pre-apocalypse weapons parts as well as other materials (pipes, crutches, other metal and wooden parts). Perhaps the previously mentioned modern-day weapons could be found but only VERY rarely and in VERY poor condition. Conventional ammunition could be scavenged, but most guns would either be zip guns or black powder.

This doesn't necessarily have to come late game either, since this technology is pre-apocalypse it could be found at any time.

2. Crossbows

I think this might already be a given, since bows are mentioned on the wiki. Just in case though, I feel I should suggest it here. Crossbows would fit in great with the current world, along with bows (bows would come first or at the same time, of course).

Thoughts?
