Stadt der Untoten/Blast From the Past

Blast From the Past is the major easter egg for the map. It must be completed to get the Acht und Ein achievement/trophy.

Requirements
For the entire easter egg, minimum of two players must be in an online party. LAN party/System Link or splitscreen do not work. However, doing a part of the easter egg is possible on solo as well, as that progress is saved for future uses. Doing the steps require lots of time, patience and teamwork, as well as some points and luck with obtaining the right weapons from the Mystery Box. Making a crawler zombie (by blowing a zombie's legs off with explosives to make the zombie significantly slower) whilst doing the steps at the end of a round helps significantly to give the player more time and freedom to do the necessary.

To complete the whole easter egg, the players must have the weapons/devices listed below:
 * 46-69-72-65
 * Semtex
 * Zombie Shield
 * Monkey Bomb
 * Bone Chiller

Step 1
"Good fools! The world will soon be saved!"

- Edward Richtofen to Samuel Stuhlinger

In the beginning of every game, all characters will hear Richtofen's laugh and, unless one is playing as Samuel Stuhlinger, a distorted voice. Samuel will hear the true voice, and remark that he is "trying his best". Although a part of the easter egg, the easter egg is only activated once a teddy bear with a sickle, which is sitting in the corner of the starting room, on a shelf, is activated. Once activated, static will be heard.
