Don't you need a little creativity to make games?

How about one player has a portal gun that shoots through a specific wall type. The other player has a regular gun, but is blocked by all wall types. The first player has to position the portals so that the second player can shoot the targets behind the walls.It's just an idea I've had in my head for a while.
The first player could have a sword that, when the fire button is held, reflects projectiles.Then the second player could have much less health, but uses weapons that have a much greater range.Encouraged teamwork = Challenging multiplayer
It's from bionic commando, durr
Guns that fire guns.
