The Blue Gate Communication Tower sits at the extreme north of the Blue Gate map, in the Pilgrim’s Peak area. The key you’re looking for is used on a locked door beneath the tower—this is a basement-level room directly under the structure.
If you’re scanning the map, aim for the far northern edge and work toward Pilgrim’s Peak. Landmarks here are sparse, so the tower itself is your primary visual anchor.
How to reach the Communication Tower basement
The most dependable approach is from above. Reach the tower’s upper platform, then use the zipline/cable to descend into the space below the tower. At the bottom, you’ll find a metal door that requires the Blue Gate Communication Tower Key. Unlock it to access a compact loot room.
If you arrive at ground level first, look for the tower’s underside access and the descent cable that leads into the basement chamber. The door is close to the tower’s base—stay directly under the structure to avoid wandering past it.
| Target | Region | Map position | Landmark | Access method | Key use |
|---|---|---|---|---|---|
| Communication Tower (Blue Gate) | Blue Gate | Extreme north / northeast | Pilgrim’s Peak | Approach from top; descend via zipline/cable | Unlocks the metal door in the basement under the tower |
Where the Blue Gate Communication Tower Key usually drops
Keys for the Blue Gate region are most commonly found on the Dam Battlegrounds map, with especially good odds around Ruby Residence and the Research & Administration Building. Check every interior: rooms, crates, tables, and lockers can all roll a key. Loot refreshes after missions, so revisiting Ruby Residence regularly pays off. Some Arc enemies—especially those guarding restricted zones—can also drop keys occasionally.
What’s behind the door
The basement door opens into a small, single-room cache with valuable loot. Expect a quick in-and-out: descend, unlock, clear the room, and extract. This is a straightforward, low-friction stop if your route already takes you along the northern edge of Blue Gate.
If you remember just one thing, make it this: head to Pilgrim’s Peak at the far north of Blue Gate, get above the Communication Tower, ride the zipline down, and use the key on the metal door beneath the structure. It’s fast, consistent, and easy to fold into your run without detouring through the rest of the region.
