Gunner Plaza

This is a heavily defended Gunners hq with turrets and heavily armed guards in the perimeter, including one equipped with a Fat-Man. It's better to take this specific gunner out first by sniping or utilize stealth and engage the guards within the perimeter.

Enter through the double-door to the west to reach the next part of the second floor. To the north, there's a novice blue utility door with a tension trigger. To the south, you'll find a Nuka-Cola Quantum inside a tray on a bench. Beside it, is an elevator that leads to the basement. The broadcasting room in the middle of the corridor has a master lock. If you can't pick it, you have to get the key from one of the two named Gunners in this location.

The office NW of the recording room has a working terminal and a wall safe. You can use the terminal to unlock the safe. The first room to the SW has a stealth boy. Both ends of the corridors Lead to a large staircase leading to the second floor.

In the corridor heading east, there's an advanced wall safe to the right, between two display cases. Take the first turn to the right (south) and you'll find an advanced blue door with a Fat-man inside. The NE room has a novice terminal that can disable the turrets. Continue to the balcony area of the main hall.
