I got an idea:
Climbable terrain. Very tall, vertical maps. 
Climb up walls and swing between points to get to the top of the map. 
Theres poisonous ooze creeping the map and if you touch it you die and lose.
Shooting other players can stun them temporarily or knock them into a direction depending on the weapon but you have to be pretty precise. You also have a grappling hook and a spear. 
Loadout be like:
>Spear
>Stun gun
>Blast rifle
>Grappling hook
Each player has a designated color and they can only grip onto their own color. And guess what? The paths converge. And split.
