This achievement/trophy is the more difficult variant of The Final Reich's storyline quest, the easier variant being Fireworks.
- The Fireworks storyline quest must be completed up until you shoot the hilt of Barbarossa's sword.
- All four Tesla Gun variants must be constructed.
Step 1 – Finding the Keepsakes
Located around the village, there are three keepsakes: a red, an orange and a green keepsake.
Once you find one, shoot it and it should drop, from which you can pick it up. You will need to place all three keepsakes in the toy shop window adjacent to the bunker doors to advance.
Step 2 – Finding the Record
Once placed, the keepsakes will have an arrow on them facing a certain direction. This represents a normal clock.
In zombie spawns, there will be codices displaying a number with a corresponding bow telling you which direction to turn its respective keepsake. Once completed, a record will pop out from a drawer underneath.
Step 3 – The Weather Vane
At the waterfront, a golden weather vane will appear. Use it and it will point in a general direction of a tiny spark. Once you have shot it, an audio cue will sound and the mill behind the weather vane will reveal a coil.
At this point, shoot any upgraded Tesla gun shot at it and it will power the windmill, which will give you access to the pub. Go into the pub and place the record onto the record player.
Step 4 – The Tesla Coil
The power switches in the Morgue and the Laboratory have been turned off. Switch them back on, as well as the power switch in front of the salt mine, to reveal a tesla coil.A Brenner head is highly recommended for this next step. Shoot the Tesla coil with an upgraded Tesla gun, this will then cut the lights.
