Get a Stun Baton Descend Into the Large Circular Room Take Out the Enemies in the Bunker Take Out the Enemies in the Long Hallway Get the Access Card from the Rosetta Heavy Open the Door in the Previous Hallway Go to the Other Side of the Room Defeat Sergeant Major Dutch III - S0012

1. Get a Stun Baton

Before heading to Silo Alpha, make sure you have a Stun Baton. We'll be needing this in the seepage zone or secret room later on!

2. Descend Into the Large Circular Room

With the Stun Baton in hand, enter the dungeon and head straight toward the open door ahead.

Carefully descend in the cylindrical room and aim for the ledge below with a storage crate. After opening the crate, look for an open door near a ladder on the opposite side.

Go through the door to reach the next area.

3. Take Out the Enemies in the Bunker

In the next area, go up the stairs to find two enemies at the top. Take them down, then go right. Follow the hallway to its end until you reach a large room with lots of enemies.

Take down the enemies in this bunker and make use of the gas tanks scattered in the area to take out multiple enemies at once.

Exit the room through the southern door afterwards.

4. Take Out the Enemies in the Long Hallway

The next area is another hallway. Turn left, then go up the stairs, killing the enemies in the hallway.

Move forward to the open door and ignore the leftside door for now.

5. Get the Access Card from the Rosetta Heavy

Continue down the hallway to reach a new room.

Clear the enemies on your current floor, then eliminate the Rosetta Heavy on the lower floor to obtain the Access Card.

Use it to open the nearby door and loot the weapon crate inside. After that, head up the stairs again and exit the room.

6. Open the Door in the Previous Hallway

Go back to the previous hallway and use the Access Card to open the door we ignored before.

Enter the room to find more enemies. Take them down including the snipers and turrets on the other side of the room.

7. Go to the Other Side of the Room

Once the room is clear, go up the stairs near the door where you came in. Go straight towards the storage crate, then jump to reach the other side of the room. You can also use the metal platforms as a bridge to get to the other side.

Use your Access Card once again to open the huge door to your left. If you're feeling brave, you can go right and explore the seepage zone first.

8. Defeat Sergeant Major Dutch III - S0012

Enter the huge door to reveal a flight of stairs. Go up these stairs, then turn left to reach a control room of some sort where the boss and his soldiers are hiding.

Focus on defeating Sergeant Major Dutch III - S0012 as the other soldiers will eventually die once their boss has been defeated.

Once the kerfuffle's over, enter the room to your right and grab your loot. Exit the dungeon afterwards.

1. Take Down the Soldiers Guarding the Seepage Zone Door

The door to the seepage zone is guarded by two Rosetta soldiers. Take them down first, then use your Access Card to unlock the door behind them and reveal the portal to the seepage zone.

2. Enter the Seepage Zone

Open the Gear Crate nearby, then enter the hazy portal to reach the seepage zone. You'll find yourself in a theater afterwards.

Continue down the hall until you reach the stage, killing the Rosetta soldiers in your way.

3. Equip Your Stun Baton and Activate All Power Equipment

Near the stage is an equipment that needs to be powered. Equip your Stun Baton and hit the equipment to power it up.

There are 4 more equipment like this that need to be powered up. You can find them by following the blue wire on the floor.

4. Defeat the Glutton

Once all 5 equipment have been powered up, a Glutton will spawn on the stage. Aim for the glowing parts on its legs to take it down easily.
