The Mystery Box is a box that gives the player a random weapon for 950 points that appears in all canonical maps (10 points with a Fire Sale) and most non-canonical maps. However, the chances of getting a good gun from the box is about 50/50, especially when the player might find themselves in a rush or trapped in a room filled with zombies. At this point, no-one knows about the box's origins, but that hasn't stopped people from coming up with a variety of theories on the box.
Whilst the box itself was introduced on Nacht der Untoten, a more prominent part, the Teddy Bear was introduced in Zombie Verrückt along with many of the other new features. Upon getting the Teddy Bear, you are automatically refunded the 950 points you have spent, and the Box then goes to another random spot on the map. However, this does not happen on the iPod Touch version. This rule has since applied for all maps except for Nacht Der Untoten.
