Totenreich doesn't hand you the Wunderbarrage for free, and that's probably fair, because the thing can wipe a lane clean when the round gets ugly. If you're practising routes, chasing weekly tasks, or just warming up in a BO7 Bot Lobby before a proper run, it helps to know the setup before you start burning points and time. The key is the Wundersignal. You'll need the Jotunn Star first, so don't skip that step and then wonder why nothing works. Once you've got it, head to the Lighthouse, climb to the second floor, and check the middle shelf by the east-facing window under the stairs. That Crowbar is easy to miss when zombies are crowding the room, but you'll need it for the next bit.

Finding the right crate
The Flak Gun Round can spawn in different crates, so this part changes from match to match. You can read the Cargo Manifest in the War Factory for a clue, though plenty of players just run the common locations because it's quicker once you know the map. Check the V-7 crate at Dry Dock, the III-6 crate on Fjord Road, the IV-3 crate inside Core Foundry, and the X-9 crate in the War Factory. Crack them open with the Crowbar. If you hit the wrong one, you'll take a short debuff, usually around half a minute. Annoying, yes, but not run-ending unless you're already boxed in.

Using the Flak Gun
When the correct round drops, take it over to Beacon Island and load it into the Flak Gun. Don't just stand there waiting for fireworks. Hit the gun with the Jotunn Star to trigger the shot. It'll fire across the map and blow apart the giant robot head at Eidskallen Landing. Make your way there as soon as it's safe. The area can get messy, so clear a few zombies before searching the wreckage. You're looking for the Transmitter,which is the part that moves the quest from scavenger hunt to puzzle work. Grab it and head for Tyr's Head.

Solving the light code
At Tyr's Head, place the Transmitter into the empty panel and watch the two lights above the main console. This is where people rush and mess it up. The left light gives you the Amplitude number, and the right light gives you the Frequency number. Count the flashes in the first sequence, then wait and count the second sequence as well. For instance, two flashes on the left and five on the right means 2 and 5 for that code. After you've memorised both sets, go to Core Foundry. Near Double Tap, find the frozen rope, melt it with a Molotov or a charged Jotunn Star shot, climb up, and enter the numbers on the dials. The Tyr P.A. will let you know when you've got it right.

Claiming the Wunderbarrage
Once both codes are entered, the Wunderbarrage Controller appears in the warehouse across from Double Tap. Pick it up, and the Scorestreak becomes much easier to access for the rest of the match. You can craft it at a table for 2,000 Salvage, and if you're the type who likes odd chances, fishing can also cough one up. It's loud, messy, and perfect when the horde starts pushing too hard.
