If you spend enough time walking around the floor of E3, eventually you'll find your way to the smaller booths on the side of the aisle. And there, mixed in with the walls of colorful Wii U Gamepad protective cases, you sometimes find some interesting ideas. At first glance, the MAG II looks like another lightgun, but in reality, it's an impressively simple controller for first-person shooters.

MAG II creator G-Mate Controller claims its new gun controller is compatible with all shooting games on the PS3 and PC. Xbox 360 compatibility is planned for the future. At E3, we played a couple rounds of Gears of War with the MAG II, and simply moving the controller in any direction changed the point of view. Walking is still controlled with an analog stick, as in similar gun controllers. And of course, the triggers and buttons are aligned with the grip.One of the more interesting features of the MAG II, beyond the ability to play a FPS without a sensor bar or secondary controller, is its myriad of settings. A dial on top of the device allows for sensitivity changes on the fly, and there's even a turbo-fire setting and "continuous melee" option. A small button the front of the MAG II calibrates the gyroscope for aiming, and amazingly enough, it worked really well.Clearly, the MAG II isn't for everyone, but it does seem like a hassle-free way to use a gun analog with shooters. G-Mate hasn't made release date information or pricing available.
