Quantum Entanglement Device

The Quantum Entanglement Device, often abbreviated to QED, also called the Richtofen Device by its inventor Edward Richtofen, is a secondary tactical grenade appearing on the Zombie map Moon.

When thrown, the QED is capable of creating many different outcomes. Upon toss, the player will spin the handle on the bottom once, and push it in. It can either "curse" or "bless" the player, with outcomes such as extra weapons, extra perks, more enemies, or a reset of points.
