Part 16

Crawl through the streets, being mindful of an explosive barrel near a wrecked car. Destroy it or back away when it's shot. Enter the building at the end.

Inside the Advent Palace, use Solid Eye to spot and disarm claymore mines and sleeping gas bombs on all four floors, especially on the stairs. Collect these items as they can be useful later. Explore thoroughly for ammo, health items, and an iPod song.

Reach the roof, collect items in the bar, and enter the hallway to trigger a cinematic. You'll meet Meryl and the Rat Patrol (including Johnny/Akiba).

After discussing mission details, Haven Troopers will attack. Snake, Meryl, and the Rat Patrol must fight their way out.

Equip the M4 or MK2 and hide behind the bar. Haven Troopers have body armor; aim for headshots to conserve ammo and time. Avoid friendly fire. Alternatively, use the MK.II from the hallway to stun enemies non-lethally.

After clearing the roof, follow the team to the third floor. Engage enemies attacking from the ceiling and sides. Use the MK.II from the restaurant/bar area (behind the bar and through the kitchen) if needed.

Continue to the next room, following Meryl's team. Ed will cover the doorway.

In the bar area, engage troopers attacking from the window and door. Jonathan and Ed will cover the rear. Johnny will remain in the corner. The MK.II is less effective here as troopers will target it, but it's still a viable non-lethal option.

Follow the team along the balcony and down to the second floor. Soldiers will attack from the second and third floors; find a hiding spot near the balcony and engage.

Meryl will stop near a cracked wall with laser tripwires. Fight the Haven Troopers attacking, one of whom throws a stun grenade, knocking out Akiba.

Crouch near Johnny and press the action button to wake him up. After he's revived and all enemies are dealt with, follow the team through the broken wall. Johnny will disarm the laser trap.

Follow the team down to the first floor. Wait in one of the doorways behind the bar for the next gunfight. A tank will break through the wall, and Haven Troopers will appear.

Use the bar for cover and eliminate the troopers with Meryl. Once few enemies remain, Meryl will leave you to finish. Clear the remaining stragglers.

Follow Meryl through to the elevator. A cinematic will play as the team descends. Enter the elevator shaft and proceed to the final area.

A final cinematic shows the Rat Patrol ambushing Haven Troopers. Meryl will provide more information on nanomachines and give Snake the location of… [text cuts off]
