I like number 5. Post apoc-e-lips with not one but TWO ww2 Japanese small arms. The type 99 rifle may be one of the best infantry riles ever made. The type 14 pistol may well be one of the worst. Both are almost impossible to find ammo for. Even if you do find any it is so expensive it is impossible for anyone but the wealthy to afford in quantity. Not only is ammunition for the type 14 almost impossible to get, the magazines are unobtainium at any price. The MP-38's carried by the girls in #8 are an interesting contrast to the Nuke Launcher one of them is packin'---Ray
Saw a tutorial once about converting 30.06(? been a while since I saw it) to 7.7mm Arisaka.
