The Xappr Gun

Now avail for preorder, this trigger-equipped, gun-shaped accessory affixes to most smartphones and syncs with several augmented-reality games (AR Wars, AR Invaders, Spray 'Em...), including soon-to-launch multi-player ATK, which was developed specifically for the gizmo and allows for laser tag-style shootouts, because let's face it, if you've already purchased a gun-shaped video game phone accessory, you have no qualms playing laser tag.
