There are controllers, there are controllers, and then there's a very special place in the world -- alongside inflatable raft -- for peripherals like the Delta Six.
Shooting (SORRY) straight for the mildly crazy Call of Duty fan, it's essentially replicating the actions of a standard video game controller, only in the most convoluted and theatrical way possible. A ton of sensors detect where you're pointing the gun at or how high you're holding it, and there's even the ability to reload in the game by reloading the gun in real life.
Due out next year, it's priced at $US89, and is actually brought to you by the same guys behind the Avenger controller clip-on. Cost to your reputation as a normal human being with friends and family TBA.
