Original Characters Trapped

 is an easter egg in the new Nazi Zombie map, Call of the Dead. It is similar to the Kassimir Mechanism of Ascension.

Process
Underneath the PhD Flopper room, there is a locked door. Once near enough, you will hear Dempsey knocking on the door asking for help. Richtofen explains that the teleporter has been over-used and that they are now trapped inside a dark room, asking the player on the other side of the door for help. Richtofen also becomes sick, puking spontaneously during your conversations.

First Step
The First step is to find a fuse, it's location is near the PhD Flopper on a desk or in the locker. Once you have it, go back to the door and insert it on the wall on the right.

Second Step
As you completed the first step, there is now light in the room allowing the Original Players to finally see. While discussing, Nikolai accidentally activates the MDT security system. The player must destroy 4 generators, signaled by 4 glowing red orbs, disabling the MDT security system.

Third Step
After completing the second step, Nikolai asks for some vodka. Outside near the PhD Flopper, there is a bottle of "vodka". One player must knife it while another player picks it up, like the Film Reels in Kino der Toten. After this, you must deliver the "vodka" to them via eartube, the device on the left of the door.

Other Steps
Nothing else is known about it at the moment.
