Totenreich doesn't hand you the Wunderbarrage just because you've got spare Salvage. You'll notice that pretty fast. This scorestreak is tied to a proper little quest, and the first wall is the Jotunn Star. Without it, you can't reach the right Lighthouse areas or wake up the machinery that starts the whole chain. Some players would rather practise setups, level routes, or even buy CoD BO7 Bot Lobby access before pushing awkward quest steps, but either way, the Jotunn Star has to come first.
Grab the Crowbar on Beacon Island
Once the Star is in your hands, head to Beacon Island and climb to the second floor of the Lighthouse. You're hunting for a Crowbar, not a flashy relic or some glowing marker. It's usually sitting on a middle shelf near the east-facing window, tucked below the stairs. Easy to miss if you're rushing. Pick it up, because this is what lets you crack open the special crates around the map. No Crowbar means no Flak Gun Round, and that means no Wunderbarrage.
Check the crates without panicking
The Flak Gun Round moves every match, so don't get too attached to one route. Start checking the usual crate spots in a sensible order. Look along the northwest wall in Dry Dock at V-7, then try the rear section of Fjord Road near the blocked path at III-6. After that, swing through the eastern warehouse in Core Foundry at IV-3, and don't forget the upstairs wall inside War Factory at X-9. If you open the wrong crate, the game slaps you with an elemental debuff for a short while. It's annoying, yeah, but it's not the end of the run. Back off, clear space, wait it out, then keep moving.
Load the Flak Gun and follow the shot
When the Flak Gun Round finally drops, take it back to Beacon Island. There's a huge Flak Gun aimed toward Eidskallen Landing, and that's where the next part happens. Insert the round into the rear of the weapon, then hit the gun with the Jotunn Star. That should kick off the firing sequence. The shot smashes into the giant robot head over at the landing, which is your cue to go there and search the wreckage. Hold the interact button until the game gives you the Transmitter quest item. Don't tap and run off too early, because the pickup can feel a bit slow.
Use the Wunderbarrage carefully
After the Transmitter is collected, the Wunderbarrage becomes available. You can build it from the Support section at a crafting table for around 2,000 Salvage, and sometimes you might even pull one while fishing if luck's on your side. It calls in a brutal missile barrage from the robot, covering a huge part of the map, so it's brilliant for wiping packed waves. It can also ruin you if you're standing too close. PhD Flopper is the perk you really want before using it. As a professional platform for buying game currency or items, RSVSR is built around convenience and trust, and you can buy rsvsr CoD BO7 Bot Lobbies for a smoother grind while you practise this step-heavy Totenreich route.
