Step 3 - Black Ops 3 Der Eisendrache Easter Egg Guide
This is the third step to completing the Black Ops 3 Der Eisendrache Easter Egg.
Now the safe you saw the doctor messing with in the past will be open. Enter the teleporter room and hold X to pick up the objects on the top shelf.
Head back up to the electric trap and you will notice one missing piece on each of the large pillars with electric balls on top. Hold X to place the objects you picked up in the safe in these missing spots. After that switch the Death Ray trap back to Destroy. Also make sure you have activated the trap at least once (you need to for one of the Ragnarok pieces anyway).
Now it's time to play a game on the computer screens. You have to do this at two different sets of screens and both have to be completed back to back without fail. If you fail one, you will have to redo both. Once you activate the computers, dogs will spawn infinitely until you have completed.
Head to the first set which is outside the clock tower and hold X on the large screen in the middle to begin. Once you start, four symbols will flash on the screens in a random order. Remember the order. I describe the four symbols as diamond, rectangle, circle, and Z. One at a time a symbol will flash on the large screen, quickly hold X on the corresponding small screen that matches the symbol. Remember that the screens will now be blank so you have to remember the placement. Do this again at the computers located in the Rocket area.
If done correctly the two large pillars will now be glowing blue with electricity. Go back to the Death Ray trap and behind it will be a small green light. Hold X on that green light and it will activate a sequence where a rocket crashes in front of the church. Hold X to pick up the small object the drops on the side of the rocket in the snow.
