You know what I've wanted for a long while? A barrier gun.
It's like a lazer you use to shoot a line on the floor or wall, and out of that line shoots out a transparent wall of energy that player's can't pass through. The wall would only be temporary, but it could have some pretty cool strategic value.
Don't want someone to run away? Shoot a wall in their escape route.
Afraid you'll get flanked soon? Put up a wall behind you?
Want to reach that ledge? Build some platforms along a wall.
