"Lost in Transmission" is one of Shani's late-game quests in ARC Raiders, and it's a short but intense mission that takes you to the Spaceport to reach Control Tower A6. Your goal is to climb to the top and use a terminal to re-establish contact with Speranza. The twist is that every objective must be completed in a single round, so if you die or fail to extract, you'll have to start over. It's a perfect example of ARC Raiders' mix of PvE and PvP tension: the path is simple in theory, but the tower is a hotspot for other raiders, and one misstep can cost you your key, loot, and progress ARC Raiders Items.

To start the quest, pick it up from Shani in Speranza after finishing earlier jobs like "Our Presence Up There." She gives you the Spaceport Control Tower Key, which is needed to access Control Tower A6. Make sure you bring the key with you into the raid—if you forget it, you won't be able to unlock the tower door. While sometimes another player may have opened the door already, relying on that is risky and can waste a run.

Once in the match, head to Spaceport and locate Control Tower A6, which is near the center-lower part of the map close to buildings like Vehicle Maintenance and Container Storage. The tower is tall, clearly marked with "A6," and there are multiple ways to approach depending on how contested the area is. Experienced players often recommend either rushing the tower early before other squads converge or waiting until the later minutes when PvP thins out. Control Tower A6 is one of the more dangerous hotspots, with AI and human raiders frequently fighting over the key room and its loot.

At the base, move through the corridors to the locked door that leads inside the tower. Use the Spaceport Control Tower Key to open it, which gives access to a zipline all the way to the top. If you don't have the key, the door might already be open from another squad, or you may find one in drawers, lockers, or as a random drop, but this is unreliable. Once the door is open, take the zipline up while staying alert for other players who might be camping the top.

At the top, climb the short flight of stairs into the main control room and find the terminal, usually on the left side. Interacting with it completes the core objective, but the raid isn't over until you safely extract. Loot the room thoroughly, as it often contains valuable supplies and even Epic-rarity items.

The final challenge is surviving the extraction. After finishing at the terminal, ride the zipline down or take alternate routes depending on gunfire, and make your way to your chosen extraction point. It's often safer to avoid obvious extraction zones if the tower area has been active, as other squads may be waiting. Once you extract and return to Speranza, talk to Shani to officially turn in the quest.

Completing "Lost in Transmission" rewards you with the Snap Hook, a legendary grappling gadget that greatly improves vertical mobility and unlocks shortcuts for future missions buy cheap ARC Raiders Coins. The Snap Hook is especially useful for quests that require reaching high platforms, like "Eyes in the Sky." In addition to the gadget, you'll likely gather extra weapons, materials, and consumables from the control room, making the run doubly worthwhile.
