New LMGs like the M250, M240, MG3, PKM.

New assault rifles like the FN 2000, G36c, AS Val, Honeybadger.

New pistols like the FN 57, M45, USP 45, H&K 45.

New SMGs like the MP7, APC9, MPX, and MP9 would be some cool weapons to see in the game.

I feel like the current arsenal is a bit small at the moment.
