Aquanium Recovery Walkthrough
Reaching Merrick Battleship
| No. | Step-By-Step Walkthrough |
|---|---|
| 1 | Leave Spino and head south towards the map marker. From there, follow the tire tracks. At the first clearing, the tire tracks will split and go in different directions, but they will connect at the end, so continue heading forward in the same direction. |
| 2 |  When the tire tracks fork into two directions, go to the right. Then, when they reconvene, turn right again and go through the West Marhan Checkpoint gate. You'll reach the city of Terigino. |
| 3 | Optional: Try to get materials from plants or creatures that you encounter along the way. These will be very helpful when you're trying to make your vehicles stronger. You can also take a break at Libr Camp just outside Terigino to recuperate. Don't forget to grab the material in the chests there too! |
| 4 | From the Terigino entrance, go northeast following the tire tracks again. When the tire tracks fork, go left towards the fortress, not towards the stone arch. From here, the tracks will occasionally fork off in different directions, but simply continue heading straight towards the quest marker. |
| 5 |  You'll reach the Royal Capital, but there's nothing to do here now. Continue following the tire tracks northeast through the North Marhan Checkpoint. Optional: You can loot the chests in North Marhan Checkpoint to get materials, a Rare 13mm Heavy Machine Gun, and a rare 7mm Machine Gun. |
| 6 | Continue north to enter Junker Market: Merrick. Take a peek inside, as you can find a chest with the Interceptor Drone Option for your Jump-Bot. The merchant outside also sells the Motorbike Blueprint 3, as well as an Antigrav Stone, a rare crafting material. |
Inside Merrick Battleship
| No. | Step-By-Step Walkthrough |
|---|---|
| 1 |  Continue up the ramp and enter Merrick Battleship. Just like in Lisab Battleship, crates here are color-coded in a way. Crates with yellow paint indicate that you should use a Jump-Bot on them and red crates are fragile ones that you can break with your Battle Tank. Use the Jump-Bot to progress ahead. In the room with the broken floor, jump down one floor at a time until you land on the sandy bottom on 2F. While progressing down, be sure to grab the chest on 3F which contains 3 Antigrav Stones. Continue to the next room and fight the robots. |
| 2 |  In the next room, use the Jump-Bot to crash through the fragile floor by pressing Square (on PS) after jumping. |
| 3 |  Continue following the marker up the crates in the next room. Grab a map of the battleship on one of the crates and an Acceleration Chip (Battle Tank) near the top where the marker is. |
| 4 |  Continue ahead while taking out Wannabe Junkers. Take two slopes leading down, then at the bottom, jump up onto the containers marked with yellow paint using the Jump-Bot until you reach the next area. |
| 5 |  Optional: In this room, you can find a fragile container which you can break with the Tank. This will open a gap into a new room; defeat the robots there and proceed. You'll enter a room with containers hanging from the ceiling which you can shoot down, then platform across with the Jump-Bot. You'll receive a few decent items like Machine Gun Scraps at the other end, but nothing world-shattering here. |
| 6 | Go back to the previous room and continue ahead until you reach a fragile floor; smash it with a ground pound from your Jump-Bot. In the room below, jump up to the opposite side to find a 20mm Anti-Material Rifle+. |
| 7 |  Ahead, climb up the containers and grab a 40mm Light Mortar and an Improved Handling Chip (Battle Tank) on the way up. |
| 8 |  In the next room, defeat the jumping robots, then proceed towards the elevator in the huge central room. Jump on the crates to reach the next area and use the Jump-Bot to jump across the gap near the Water Supply Station. Defeat the jumping robots and wannabe junkers in the next two rooms. |
| 9 |  Break the fragile floor in one of the rooms using your Jump-Bot to fall through the lower floor. Follow the marker up a slope to a new room. |
| 10 |  Continue platforming through subsequent rooms until you reach a couple of crates stacked on top of each other. Jump on top of these crates and climb up the slope. Defeat the jumping robot in the next room and grab the Parallel-Twin Turbo Engine II before exiting. |
| 11 |  Continue following the quest marker until you reach the elevator. In the next room, you'll fight the Defense System. Defeat it to receive 800 EXP and 1,500 Zeni. |
| 12 | Head back and take the elevator down. Continue ahead to reach the exit. |
Rosetta's Brigade
| No. | Step-By-Step Walkthrough |
|---|---|
| 1 | Fast travel back to Spino and talk to Mayor Tor. |
| 2 |  Leave Spino and advance to the map marker. Destroy all of the tanks. |
| 3 |  Walk into the tunnel and get the Aquanium, and bring it back. |
| 4 | Go back to Spino and talk to Are to finish the quest. |
Aquanium Recovery Boss Guide
Defense System
The Defense System is a tanky robot capable of controlling some aspects of the room it's in. It has limited movement though as it can only move back and forth along the perimeter of the battle area.
Here are some tips to defeat it.
Use Your Machine Gun on the Small Drones and Your Primary Weapon on the Defense System Itself
The Defense System sends drones your way every now and then. Take these out using your second fire, so you can reserve your Primary Weapon for the Defense System itself.
Don't Bother Taking Out the Small Turrets
You should be able to move along with its lasers while also avoiding the lasers from the turrets; don't bother taking out the turrets as they will simply come back on the next round.
Predict Its Movements
Focus on predicting its movement and aiming armor-piercing bullets at it with the Battle Tank. Since it's just moving back and forth, it should be easy to hit it with your gun.
Move on Higher Platform To Avoid the Electricity on the Ground
At one point, the floor you're on will be charged with electricity which can damage your tank. Avoid this by hopping on a higher platform using your Jump-Bot. Then, change your vehicle back to the tank and shoot the Defense System until it dies.
