I don't mean to make an ambiguous topic, but here is my idea.
I was thinking of a brick, and when you step on it, you gain control of a flying/hovering robot, and the robot has a gun (any kind) mounted to it. I thought this would be good for exploring dark zombie filled tunnels, and fighting in tight spaces.
Anyone who has seen a controllable, deployable turret, like in Tribes 2, should know what I'm talking about.
