Ninja Gaiden 3 Walktrough Part 4 – Day 2, Part 2 – Rub' Al Khali, The Deserted City
After the hawk Ryu wants to move forward and Bird Flip upwards. Move to the end of the next ledge and use the bars to traverse the gap. The floor will collapse on Ryu as he lands on it. This throws him into battle against a few Terrorists hidden in the depths of the building. Kill the first group and move forward. A few Assassins, or worse, are waiting ahead. Just as Ryu passes through the next archway, start sliding to avoid one coming right at him. After the second group Ryu wants to head to the door at at the of the stairs at the end of the hall.
Head through the door into the street. Move forward until prompted to fire an arrow. This will begin a battle against a number of Alchemists. These are some very hard to beat enemies. First, when their hands are glowing blue, attack them with Strong attacks as they will deflect anything else. If their hands are glowing black they are going to use their powers offensively. When Ryu starts attacking them it is best to lead with a Strong attack then switch to Quick attacks. Be wary of their grabs as they can drain both life and Ki. These are telegraphed by their hands glowing red. Be sure that you focus more on a single Alchemist when Ryu engages them as they are hard to kill.
After the Alchemists are dead then climb up the nearby white wall. There is a Falcon on this level you can use to save. After the second climb, a cutscene starts with a few prompts in it. Jump then Kunai climb into the hole blasted into the wall. When Ryu gets into the hallway, just start moving forward. Head forward to the left then right. Approach the Jukebox in the back-right corner of this room. As Ryu enters the light around it, block. Assassins will drop down from above. They are, of course, backed up by some Terrorists. A few of these have Rocket Launchers of course so be ready for some dodging as well. Of course Jump and fire at them to avoid the worst of the possible damage.
After Ryu deals with everyone inside that room then more will come out from a shutter that opens to the right of Jukebox. Some Shield Terrorists with the regular variety will come at Ryu (With some Alchemists at the right difficulty). Head through the shutter that opened on right-hand side of the room. Continue on through toward and into the light ahead.
Continue up the stairs to the left. At the top, move forward and use the bow to kill the terrorist on the far side of the gap. After that, have Ryu Wall Run across then go down the corridor to the right. At the end of the next corridor. When you get to the massive window, a helicopter appears to attack Ryu. First and foremost, DODGE. Start sliding immediately to avoid taking damage from the wall of bullets and missiles coming at Ryu. Ryu can pause to jump and shoot an arrow during these. Still, it is better to wait until the Pilot comments on the need to reload missiles. Then it is possible to unload between 3-5 arrows at the Helicopter. Just keep shooting them until it ascends to a different level of the complex.
After it flees, start away from the window, going toward the stairs in the back of this massive room. Slide underneath the column and Ryu will be re-engaged in combat with the Helicopter. Follow the same tactics to take it down.
After it has fled for a second time, head to the right and slide through the gap at the bottom of the fence there. Go left when Ryu enters the Monorail station. Slide under the burning wreckage, fend off an ambush then approach the Hawk to Save and Heal. Now head to the left onto the monorail itself.
After a short pause, the terrorists and helicopters start at Ryu again. This batch has a new type, Jetpack Heavy Soldiers. These are especially annoying as they have flamethrowers to deal with. Any that land on the train, try to shoot with arrows. To kill them, it likely takes 3 arrows. If they close the gap or make a nuisance of themselves then kill them quickly with the sword. Between the waves, jump and fire arrows at the Helicopter. Between the waves of Jetpackers, move and shoot arrows at the Helicopters. Once Ryu has dealt with, at least, a pair of them then another cutscene triggers. Follow the prompts to jump and glide to safety.
