enhance the physics a bit.
I know this game is supposed to feel different than other shooters, which is why I am not entirely for things like holding more weapons and whatnot (maybe 4 guns, and it would help sales of weapons too).
I was thinking that the jumping should be fixed so that it felt smoother, because in all honesty it feels like the top of my head hits the ceiling every time I jump.
Also, there should be an empty weapon auto-switch option or at least a warning so that you at least don't have to worry too much about running out of ammo during a fight. That and when you pick up a new weapon you can only carry it for a little bit, which, in my opinion, makes picking up opponent's weapon's kind of pointless.
