I was just cogitating on the spinach being the only power up in the game thus far, and was thinking they could add some kind of power up that would let you pick up weapons more easily for a short time. No ground grabbing or fighting with others for a weapon. Maybe you could double click a button and the nearest weapon that isn't in someone hands comes to you.
Just a thought though. Maybe it sucks, maybe it's too good. I haven't really thought about it for more than a couple minutes. Thoughts?
