Introducing Ziggy

After the worlds second longest set of cut scenes, you’ll have control again. This time, however, you’re not Shion. You are now Ziggurat Industries “Ziggurat 8”, soon to be known as ZiggyCharacterPlayable cyborg commonly called Ziggy.. You’re invisible, so don’t worry too much about being seen or heard, actually.

Head slightly right and save your game. You don’t REALLY want to watch the whole cut scene again if you screw up, do you?

After that, head up the ramp and directly right. You can blow up some stuff here to get a ScopeCharacter AccessorySearch Eyes (Display Enemy information) (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.). From where you get the Scope, head maybe two steps up and blow up the red barrel for Ether Upgrade SItemTarget: 1, +50 E.Pts x2 (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.). Go examine the A.G.W.S. if you want, then try to go up the ramp to the upper right.

Watch the cut scenes and then you get to have some real fun. You have to make your way right. You’ll want to hold down R2 to keep your footsteps from echoing and bringing the enemy running. If you head up the stairs at the top of the screen, you can get a feel for what the layout of the area looks like. Essentially, you’ll want to run, er no, walk to the right without walking into a guy. I usually watch to see which way the guys are walking, then step into their pattern.

On the next screen to the right, blow up the object at the bottom-left for ReviveItemTarget: 1, Revive KO'd ally with HP recovery/Low x2 (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.). At the top, there are two objects you can destroy. Blow them both up, and they’ll reveal a doorway heading left. Go left and walk behind the wall until you get to the chest. There’s a Snake HunterCharacter AccessoryPoison Guard (Prevents Poison) (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.) in there. Equip it. Just above the chest is a wall you can blow up, behind which is hidden Segment Address 4SidequestSegment Address 4 is opened with Decoder 4.. Found it You can open Segment 4 in the full tracker at any time.

Head back down the hidden corridor and slowly walk past the guard at the top. Just past that fire pit, you can hide in a little walkway at the top and wait for the next guy to go past. Follow him all the way around his fire pit and you can get by without being seen.

Go on to the next screen to your right. Just so that you know, in the center of this screen is a hidden chest containing Decoder 11Key ItemItem required to open Segment Address No. 11. Blow up the large object in the middle to reveal it Got it, but be ready to fight a LOT of guys if they notice. You can open Segment 11 in the full tracker at any time.

Walk all the way across the walkway and, on the next screen, read the sign. Wander to the bottom-right corner and listen to what Ziggy says about the A.G.W.S. there. You need to distract it. On the lower-left is a crane. Hmm… Why don’t you try pressing that switch?

While the A.G.W.S. is looking at the remains, head back to the right and go down the ladder. Incidentally, defeating this Mercurio-ABoss-like Enemy640 HP; Mechanical type. Weak to Lightning is effective; formal weakness unconfirmed. Rewards: 150 XP; 10 T.Pts; 4 E.Pts; 6 S.Pts; 200G. Drops: Med Kit S and Decoder 4; no rare item. Strategy: Keep MOMO behind Ziggy and use Sheep Beam whenever Mercurio-A wakes. Guard through Absolute Defense, then use Lightning Fist before putting it back to sleep. later gets you Decoder 4Key ItemItem required to open Segment Address No. 4, which will net you a Thief RingCharacter AccessoryRare +10 (+10% earn better items in battle) from Segment Address 4SidequestSegment Address 4 is opened with Decoder 4.. Keep going right onto the next screen.

Watch the cut scenes and get ready to fight. You should be able to take these guys no trouble. My Ziggy started with over 400 HP, though.

Meet MOMO

After the battle and ensuing cut scene, that’s MOMO, btw, you’ll need to find the Master KeyKey ItemRequired to open MOMO's holding cell on Asteroid Pleroma.. Head down the stairs at the bottom-left of the screen. On the next screen, you can avoid the people and robots if you are careful.

Go down the stairs and collect Veil x2 from the chest just beyond the yellow canister (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.). Then head straight back to the right along the top wall. Just past the vehicle, you’ll find some boxes you can blow up, and just down from that is a doorway. Go through it.

On your left is a room with six boxes:

• The lower-right has 1x Bio SphereItemTarget: All, HP & EP full recovery (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.)
• The upper-right has 1x Ether Pack SItemTarget: 1, EP recovery/Mid (+20 EP) (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.)
• The lower-center has 1x Med Kit SItemTarget: 1, HP recovery/Mid (150 HP) (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.)
• The upper-middle has 100G (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.)
• The upper-left has 1x ReviveItemTarget: 1, Revive KO'd ally with HP recovery/Low (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.)
• The lower-left, however, hides Cyber Crabs. I don’t recommend fighting them.

Head back to the hallway, and go through the door on your right.

Gardis M1

Fight the Remote Activation Unit, Gardis M1Enemy450 HP; Mechanical type. Weak to Lightning. Rewards: 350 XP; 10 T.Pts; 0 E.Pts; 8 S.Pts; 0G. Drops: Med Kit S; no rare item.

In the chest up and right of where that robot was, you’ll find the Master KeyKey ItemRequired to open MOMO's holding cell on Asteroid Pleroma. (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.). Heal up, then head back to MOMO the way you came.

Unlock the door to the left of MOMO’s cell first. There’s a save point in there. The next cell over has a Speed StimItemTarget: 1, Speed +25% (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.) in a box. Now go open MOMO’s cell and say hi.

Try to go back the way you came, and you’ll have to turn back. Instead, take the path down and left. Have MOMO use her healing Ether, Life ShotEtherMOMO: Medium HP recovery for one ally or enemy., and have Ziggy attack if you get in battles. Head down and right to the door again, then go into the control room. When the cut scene ends, press the red button on the right-hand counter, head out through the door, cross the hall, and go down the ladder.

Sewer and chapel

Watch the cut scene, then head left. Blow up the red object beside the first door for a Med KitItemTarget: 1, HP recovery/Low (50 HP) (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.), then go through the door into the chapel.

When you’ve collected the stuff here, head back to the corridor and continue left. Destroy the second red canister for a ReviveItemTarget: 1, Revive KO'd ally with HP recovery/Low (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.).

Once you acquire 60 Skill PointsBattle SystemBattle reward spent to extract Skills from equipment., be sure to get the Poison GuardSkillPrevents Poison. Skill.

When you get to the slick pipes, you’ll want to walk with R2 and use the directional pad instead of the control stick. It’s a lot easier that way.

Continue on and pick up the Ether Pack SItemTarget: 1, EP recovery/Mid (+20 EP) (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.) from the destructible object in the next section. At the far end, BE SURE YOU ARE READY TO FIGHT, then head up the ladder.

Remember, Ziggy can throw an Ether PackItemTarget: 1, EP recovery/Low (+10 EP) to MOMO. If you can keep them asleep, it’s much easier. ;)

As soon as the battle’s over, be sure to adjust your items, if you need to. You can get:

• 2x Bio SphereItemTarget: All, HP & EP full recovery by blowing up the forklift (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.)
• 8x Med Kit SItemTarget: 1, HP recovery/Mid (150 HP) from the chest (Got it:Mark this treasure as collected. Open the Treasure Tracker for the complete list.)

Yup. 8x. Wow.

There’s nothing else to do here or back, so head to the upper-right and into the command room. First things first, save.

Decoder 4 and Segment Address 4

Use the Battle Formation menu option to place MOMO directly behind Ziggy if you aren’t going to level up a bit. Head out the door at the top of the screen and fight some soldiers. You can level up, then go back and save as much as you want here.

FWIW, I actually head right all the way to the Mercurio-ABoss-like Enemy640 HP; Mechanical type. Weak to Lightning is effective; formal weakness unconfirmed.

Margulis

When you’re ready to go on, save in the control room, place MOMO behind Ziggy in the Battle Formation screen, and use items to restore your health and Ether. Be aware of what accessories you have equipped. If possible, try not to equip anything you don’t have duplicates of so that your future characters can learn their Skills.

To get to the next boss, head out the door and quickly go left at a walk. Watch the cut scenes, and get ready to fight. This guy is tough.
