Triple wielding would come in handy for Overkill. Maybe we can add a juggling animation then, too?

Triple wielding would probably be too complex, and also not make sense since you only have two hands (both logically and on the player model). A solution of course might be to imply something I'd rather not say

If it's possible still, the number of weapons you can wield at once could be turned into a cvar! Its value would be 1 by default (just one weapon, normal behavior) but people could set it to whatever they wanted. You could then have an arsenal of weapons shooting all at once, which might look pretty neat actually
