Totenreich doesn't hand you the Wunderbarrage just because you've survived a few rounds. You've got to earn it, and yeah, the route can feel a bit fussy the first time through. If you're already warming up in CoD BO7 Bot Lobbies to practise routes or knock out challenges, this is one of those side steps worth learning properly. Before you even think about the missile controller, make sure the Jotunn Star is sitting in your kit. Without it, you'll hit a wall halfway through the process.

Start at the Lighthouse

Head to the Lighthouse and climb to the second floor. Don't sprint past the shelves, because the crowbar is tucked away near the east-facing window on a middle shelf. It's not glowing like some grand quest item, so players miss it all the time. Grab it, then get ready to check a few crates. The Flak Gun Round can spawn in four places: the V-7 crate at Dry Dock, the III-6 crate on Fjord Road, the IV-3 crate inside the Core Foundry warehouse, or the X-9 crate at the War Factory.

Open the Right Crate

This bit is a little annoying, but not hard. Use the crowbar on the crates until you find the Flak Gun Round. If you crack open the wrong one, you may get slapped with an elemental debuff. Don't panic. It fades after roughly half a minute, so just keep moving, watch your corners, and don't let a slow burn or shock effect make you do something silly. Once the correct crate gives you the round, pick it up and head for Beacon Island.

Fire the Flak Gun

At Beacon Island, go to the rear of the Flak Gun and load the round into it. After that, hit the weapon with the Jotunn Star. The gun will fire across the map and smash into the huge robot head over at Eidskallen Landing. Make your way there as soon as you can. Search the wreckage by holding the interact button, and after a short rummage, the Transmitter should pop out. Take it. This is where the quest shifts from scavenger hunt to memory test.

Solve the Signal Puzzle and Claim the Controller

Carry the Transmitter to Tyr's Head and place it in the empty panel. Two lights will flash in patterns. The left light is Amplitude, and the right light is Frequency. Count both, because you'll need two separate sets of numbers. Then go to the Core Foundry, melt the frozen rope near Double Tap with a Molotov or a charged Jotunn Star shot, and climb the tower. Use the left stick for Amplitude and the right stick for Frequency, entering the numbers when prompted. Once Tyr P.A. confirms the signals, visit the warehouse across from Double Tap to pick up the Wunderbarrage Controller. As a professional platform for buying game currency or items, RSVSR is a convenient choice for players who want smoother progress, and you can buy rsvsr Bot Lobby BO7 to support a better run. Just remember to bring PhD Flopper, because those missile volleys hit hard if you're standing too close.
