Part 25

In the room where you kicked the door open, turn around. Head up the first set of stairs and take cover behind the first pillar on your left. Wait for the grenade to land at the gate's door and blow it open. Snipe or Lancer the Locusts coming through. If they get too close, use the shotgun. If desperate, run into the water and take cover. Wait for Locusts to come to you or poke their heads out, as their one-hit kill punches (on Insane) are dangerous.

Hunt down any remaining Locust in the basement if necessary.

When the door opens, head back inside. After the cutscene, head back upstairs.

In the hallway, be aware of two Wretches. Take either path back, picking up respawned Longshot ammo if needed. Take out the Locusts down at the door and head upstairs.

Prepare for a Wretch fight. To make it easier, head out into the hallway just far enough to make the Locust shut the door. Wretches will emerge from four holes in the room where you chainsawed the desk for the Cog Tag. You can fight them there or retreat to the room with the wheel that opened the basement gate. Stand at the door with your Gnasher and eliminate any Wretches that try to come through.

Once all Wretches are dead, the Locust opens the door back up. Snipe him from the hallway or use the Gnasher or Chainsaw up close.

Head through the hallways. In the main hall, head upstairs and to the right towards Dom and Cole.

Snipe a few enemies outside if desired. An invincible Boomer will appear and blow the door open.

Lancer on Hardcore/Insane: Stay upstairs and pick them off from mid-distance, or take cover on the staircase pillars. Use the Shotgun if they get close.

Longshot (any difficulty): Take cover upstairs on a pillar or rafters and snipe enemies as they come through. Plenty of ammo is available upstairs. Watch out for Theron Guards.

If the Boomer is the last enemy, avoid the shotgun due to close quarters. Use the Lancer or Longshot.

When you receive the radio transmission from Baird, load up on ammo and head downstairs. Another door will be busted open by a Locust, best taken out with the Chainsaw.

Go to the back of the house and try the locked door. Head upstairs, dodge debris, and kick open the door at the end of the hallway.

Take cover behind a window and start sniping, or throw a grenade into the Emergence hole.

After eliminating all enemies, shoot the planks holding the door below shut with your pistol. Pick up ammo and head back to that door, which should now open.

Take cover and snipe the Locust with the magnum that enters.

Head inside the door the Locust came out of.

Timed Objective (30 seconds to reach the APC): Two Boomers and an Emergence hole appear. The timer starts when the Emergence hole appears or one Boomer falls.

• Casual/Hardcore: Head outside through either door and make a run for the APC. Running quickly can get you there before the Emergence hole appears.

Insane: This part requires luck and skill.

• Attempt to head right and take cover. Sacrifice yourself once to estimate Longshot bullets needed for a Boomer.

Repeat, but use one less bullet. Get close to the halfway mark for the Emergence hole and shotgun the Boomer until it falls.

Run along the cover on the right side, crossing your fingers for luck.

The Longshot strategy is recommended for the rest of the level on Insane.
