How can we be sure any of these will actually be used though?
The AK seems like it would function far too similarly to the Bullpup, though I could see it being a longer range weapon with less ammo; You can already throw grenades pretty far already and if the enemy is too far, there's the LAW; As for the Katana, it seems pointless since we have only just twice as many guns as melee weapons roughly, yet 5 times as many perks that use guns rather than melee weapons. As for the Beserker perk, Chainsaw > everything, so why bother? While they might be good ideas (or not so much with the katana imho) they aren''t really needed. Personally, I'd rather they added some kind of Auto-pistol or another Firebug weapon of some kind.
