Everyone else will probably be completely against this, but I'd like to see some more realistic visuals. Rather than having those big blocky floating guns, why not put in some scale guns with physics (they will fall/slide according to where they land).
Also, when a player dies, instead of falling over and disappearing it'd be cool if they'd throw down their gun and walk, head hanging, back to base and then wait till they can respawn. Then, if someone shot them (it'd happen) they could face that direction and shake their fist.
Finally, does jitspoe plan to show each player model carrying whatever gun they've picked up with hopper/barrel as a pose to always carrying the carbine. This could not only look better, but show who has what gun.
