Move Ziggurat 8 to the right and use the save point. Because of his stealth cloak, you don't need to worry about avoiding soldiers, and can even eavesdrop on their conversations. After saving, go up and then to the right and you'll find some destructable boxes (hey! how did Ziggurat 8 get Shion's Vaporizer Plug-in!?). Detonate the boxes to obtain a scope, and 2 Ether Upgrade S. Then head upwards until the game enters yet another cinematic.
Walk to the left (hold R2) and avoid the guards. If you do get into a battle, kill the U-TIC Soldier that has the Mustard Bombs first- they have the ability to poison you, which could very easily spell death for you this early in the game.After you pass through the first archway, head upwards to detonate two boxes, revealing a secret passageway to the left.
Take the hidden passage to find a treasure chest containing a Snake Hunter. Equip it on Ziggurat 8 to give him immunity to poison (no longer need to worry about those mustard bombs ^_^). Detonate the stone tablet against the wall to reveal Segment Address No. 4. Go back down the stairs.
This second section is trickier to sneak past than the previous one- especially if you want to detonate the object in the middle of the room, and retrieve the Decoder 11 it contains. But the item is worth getting, even if it means you have to fight a battle or two. After you've gotten it, continue to the right.
Who in the world is chanting? I know, Pleroma is a shrine for an ancient religion- but that religion doesn't even exist anymore... so who in the world is chanting?! U-TIC soldiers? Sounds unlikely. Anyway, keep going to the right. You'll notice a treasure chest in the room below the bridge, but you won't be able to pick it up just yet.
To avoid a battle with the A.G.W.S. unit, go to the left and activate the crane. This makes the A.G.W.S. unit move away from the stairs, and also makes a treasure chest available on the floor below. Go down the ladder and then through the doorway on the right. After defeating the soldiers guarding MOMO's cell, MOMO tells you that you'll need to find the master key to unlock the door, so that the alarm won't go off. Now take the exit to the lower left. Go down the stairs and to the left to get 2 Veil from the treasure chest the crane knocked over. Now take the exit at the lower right.
In the room to the left are six boxes you can detonate. They contain Ether Pack S, Bio Sphere, 100 G, Med Kit S, and a Revive. The sixth box (in the lower left) contains a Cyber Crab- might want to avoid that one ^_^. Now enter the room on the right. The machine you see (Gardis M1) is guarding the Master Key. Make sure you are healed, and head in to take it out. The best strategy is to attack the main body with a single attack, end your turn, and on the next turn use your BMP55SX to damage the Gardis M1 and destroy both of the Gardis M10's that were generated the turn before. You can only do this twice, after which you should just focus on attacking the Gardis M1, seeing as the Gardis M10's will just keep appearing after you destroy them. After the battle, grab the master key from the treasure chest, and head back towards MOMO's cell. Open the two other cells before opening MOMO's. The cell on the left contains a speed stim, and the middle cell contains a save point.
