Well, it's a little more than a week to release date, but I'd like to ask for one more weapon (actually two) in the game.
First is
SA-50 sniper rifle present in earlier games. Sadly I didn't find it in current weapon list, and next to MG42 it was my obvious weapon of choice. I'd love to see it back.
The second one -
M388 Davy Crockett sized down to be able to carry it. Lovely, useless (in real life with original size) micro nuke. Could nicely fit in game's grotesque approach for some weapons and could be a unique, exotic weapon able to clear a small outpost (at least that's what I would try with it :) ).
