Call of Duty: Black Ops III

There are 4 wunderspheres, each of them requires you to activate it's corresponding landing pad, before you are able to use it. The wundersphere is basically a machine that launches you across the map to a landing pad. Basically use every wundersphere twice (or more) in a single game.

So before you can use a wundersphere you need:
- to activate it's corresponding landing pad (by pressing while on the landing pad)
- to have 500 credits

4 wunderspheres x 2 uses x 500 credits = 4000 credits you need. (on top of the costs for opening all doors)

Here's a video of all the locations of the wunderspheres and landing pads:

Landing pad 1 + Wundersphere 1
Landing pad 2 + Wundersphere 3
Landing pad 3 + Wundersphere 2
Landing pad 4 + Wundersphere 4

Landing pad 1: Located at the spawn
Landing pad 2: Located inside the castle, in the north-east (near wundersphere 2), if you turn right from the spawn, open 2 doors, then head upstairs. (above double-tap)
Landing pad 3: Located inside the castle as well, in the north-west (near wundersphere 3), in front of the bell tower. (the one with a painting inside, and where you start the upgrade quest for the fire bow) (courtyard)
Landing pad 4: Located at the rocket launch site.



Wundersphere 1: Located at the rocket launch site
Wundersphere 2: in the room next to launching pad 2. (above double-tap)
Wundersphere 3: Located in the same area as launching pad 3, but down the stairs and then on your left hand side. (courtyard, in front of the church)
Wundersphere 4: Located next to one of the PaP parts and next to the electrical floor trap.

This achievment is pretty easy, it requires you to fling yourself using each wundersphere twice. There are a total of 4 wunderspheres around the map, so you have to use one 8 different times. It costs 500 points each time so in total you will need 4000 points (excluding doors and weapons).

The way the wunderspheres work is you enter them and hold and they launch you across the map to a specific area. In order for this to happen, the landing pad corresponding to the specifc wundersphere must be activated. So there are also 4 landing pads that you need to activate to do this. They look like big red metallic circles on the ground and holding on them makes them glow blue.
The 4 wundersphere machines and their corresponding landing pads are:

1.Wundersphere: In the room above double tap, near a buildable table at the end of a corridor
Landing pad: On the battlements of castle. In front of the entrance to the clock tower.
2. Wundersphere: On the battlements right next to the activation for the death ray, just up the stairs from the previous landing pad.
Landing pad: In the rocket test area. This can only be acessed at first by using the teleporter for 500 points located in an adjacent room to the pyramid room. When in the rocket test area leave the safe zone with the teleporter and you'll see it immediately on the floor on the right.
3. Wundersphere: Also in the rocket testing area in the back right corner when facing the rocket from the teleporter.
Landing pad: In the spawn room on the bottom floor. If you are facing the tram controls it is behind at your 5 o'clock.
4. Wundersphere: In the upper courtyard. The area right underneath the clock tower and the church. If looking at the church it is on your left side, it is easy to spot, but to enter it you must go in from the back.
Landing Pad: Just outside the room with the first wundersphere, above double tap.

So actviate all the landing pads and use each wunderpshere twice and the achievment is yours.
