The Killer Eye is a new item in Kid Icarus: Uprising. It is a turret-like item that can be set up in front of the player. When deployed, it will fire an energy blast in the direction it is facing at a set interval, though it will fire faster if there is an enemy in its line of sight. After about a minute, it will disappear. Killer Eyes can be dropped by enemies or found in Treasure Boxes.
A compact, movable turret. Any who enter its field of vision are showered with a relentless stream of shots. Press the attack button after picking it up to place it in front of you. It can't attack targets directly behind it though.
The Killer Eye is an item in Super Smash Bros. for Nintendo 3DS/Wii U. It serves as a similar function as they do in Uprising as an offensive turret, but it can be turned around by being attacked and can also be placed on walls.
A compact, user-friendly turret. Take the name literally—anything in its field of vision will be showered with a storm of bullets. But if you placed it, it'll be your friend! If you didn't, sneak up behind it and grab it to make it yours!
