Final Fantasy XIII-2 Walkthrough

Main Story Walkthrough: Augusta Tower 200 AF

Return to the terminal that you couldn't access before. This time, with the Access Card in hand, a platform will raise from below and allow you to venture forth. Head east to talk to Alyssa. Turns out she's actually a duplicate. Head southeast through the room with Chocolina. Open the treasure sphere for a Twist Headband accessory. Run counter-clockwise from there and activate the terminal outside room #3. Access the computer inside this room for a side-quest, Find Paradox Agent Type A. Now, head to the middle ring and use the terminal across from Alyssa to create a path to the inner circle.

Talking to her will lead to a LTE:

I chose A.

Next, talk to Alyssa when she's on the elevator. She'll take you to the top floor of the tower. During your trip, you're forced into battle against a Vespid Soldier, Orion, and Zwerg Metrodroid. After that, there's another battle with three Vespid Soldiers and an Orion. These are all considered common enemies and are not necessarilly difficult. There's even a third fight; this time it's four Metrodroids and an Orion.

Then the Alyssa dissapears and you're left at the top of the tower. There are four terminals within the inner ring. Each one controls a different room on the map. You'll use every terminal to complete the paths on this floor of the map. Activate them as follows:

Toss mog of the NE corner to collect a Casino Ticket. Take the southeastern route and open the treasure sphere nearby for a Bloodguard accessory.Head to the other end to collect a Silence Gate Seal from the treasure cube towards the east. From here, begin to follow the path towards the goal using the previously rotated rooms. When you first get there, rotate the room with the small terminal inside so you can access the middle ring. After exploring that portion of the map, return to the room. When you get to the [!] marker, access the terminal at the desk. You'll acquire Access Key 52, and an activation panel will appear within the elevator.

Navigate back to the elevator and head for the 52nd floor. Once you get there, there's a LTE:

Head northwest towards room #3. Enter and go through the door on the right to get a treasure sphere containing 1450 Gil. Return to the inner circle and go southwest. Toss Mog to collect the treasure sphere with Eight Mana Engines in the center ring while facing north. If you do a 180 degree turn from there, you can explore the rest of the mid-ring to collect eight Vitality Orbs from a treasure sphere in the east. Continue through the southwest room. Toss Mog south to open the treasure sphere containing a Platinum Casino Ticket. Return to the room and use the terminal inside to rotate the room into the proper position. Use the southeast exit to grab a Magistrel Crest from the treasure sphere, then go through the other exit.

Go into the western room and rotate it twice. Use the eastern exit and then access the terminal on your left to rotate the next room into position. You are now in the outer ring, toss Mog southwest to collect 200 Gil from a treasure sphere. Next, run clockwise 'til you reach a deadend and a TS containing a Phoenix Blood item. After that, head into the room with the goal marker and access the computer for the Top Floor Access Key. With that in your posession, return to the elevator.

As you ride to the top floor, you'll encounter a Greater Behemoth. He looks formidable, but he's relatively easy. When he stands up, he begins to dish out physical attacks on your party, so perhaps bring a medic to the battlefield if you need to replenish your health. He's tameable, so if your lucky, you might catch him for personal use.

Once on the top floor, you'll find Chocolina to the N. In front of her is a treasure sphere with three Potions. Head up the stairs right next to her to continue your pursuit of Caius. At the top, you'll see a gate, and Yeul in the middle of the room.

Before you head over there, consider levelling up your party. I did not at the point, but it might be a good idea if you've accumulated a lot of CP.

Now, head towards Yeul and she'll hand you an Artefact. You'll enter the gate and reappear in the middle of a large circular room. All of a sudden, you're attacked by the Proto Fal'Cie, Adam.

Start by taking out the left and right manipulators with magic. After that, focus on staggering Adam. For a boss, he'll go down rather easily. Of course, this was only the first round.

In round 2, he'll buff himself and the manipulators. When he casts Gate of Babylon, switch to a Sentinel centric paradigm as quickly as you can. If you fail to beat him during the first stagger of this fight, he'll regenerate the manipulators. In my case, his health was low eough where I could ignore the sidekicks and finish him off. If his health is still high, take out the manipulators so you aren't overwhelmed.

Perfecting the CAS nets you a Crystal Apple adornment.

Choose option 3.

Once that's done, take the Artefact of Rebirth Yeul gave to you, and enter the gate to unlock Academia 4XX AF.
