Quick Guide
| 1 | Fight your way through the A.o.A members and get to the Master Room. |
|---|---|
| 2 | Defeat Vemmon in front of the Master Room. |
| 3 | Defeat the Game Master at the A.o.A Headquarters. |
Admin Center B1F
After heading through the gate in the sewers, you will find yourself in the Admin Center’s basement.
Walk forward from the entrance and you will be challenged by an A.o.A Trooper.

| A.o.A Trooper (B1F) Details | |||
|---|---|---|---|
| Digimon | Elemental Weaknesses | Neutral Damage | Elemental Resistances |
| Raremon | Wind | Fire, Ice, Water | Darkness, Machine, Thunder |
| Cyclonemon | None | Darkness, Fire, Ice, Machine, Thunder, Water, Wind | None |
Raremon can freeze your Digimon with its basic attacks. This is the only mechanic you will have to watch out for in this fight.
Although they are both quite tanky, neither Raremon nor Cyclonemon will hit particularly hard. Since the battle will probably drag on for a bit, heal through the damage as necessary.
After defeating the first Trooper, turn right and continue to the end of the path, where you will be stopped by another Trooper.

Defeat him, then climb up the ladder to continue.

Past the ladder, continue along the linear path and walk up the stairs.

Turn right once you get to the top of the stairs and continue right to take on another Trooper.

Once you defeat the final Trooper, continue to the end of the path to access the next area.
Basement Stairs
Walk forward from the entrance and you will run into another Trooper.

| A.o.A Trooper (Basement Stairs) Details | |||
|---|---|---|---|
| Digimon | Elemental Weaknesses | Neutral Damage | Elemental Resistances |
| Guardromon | Thunder, Water | Darkness, Fire, Wind | Ice, Machine |
| Tankmon | Thunder, Water | Darkness, Fire, Wind | Ice, Machine |
Guardromon and Tankmon are both similar, carrying the same weaknesses and strengths. The two machine Digimon are also quite frail, and will probably go down in one hit.
On the other hand, both Guardromon and Tankmon hit incredibly hard, dealing between 800 and 1,200 damage per hit.
Since both will usually go down quickly, you probably won’t have to deal with more than one attack per fight. Just be prepared to heal through the damage.
Continue to the end of the linear path, then walk up the stairs. Once you get to the top of the stairs, you will fight another two Troopers.

After defeating the two Troopers, continue to the end of the path and head over to the next area.

Admin Center 1F
You are now back on familiar territory. This is the same Admin Center from earlier in the game, although it’s crawling with A.o.A members this time.
Walk forward from the entrance and you will be challenged by another Trooper.

After defeating the troopers, continue forward until the end of the hall.

Once you get to the end of the hall, you will be challenged by another Trooper.

After defeating the Trooper, continue up the two sets of stairs to access the second floor.

Admin Center 2F
From the second floor’s entrance, turn right and fight the Trooper here.

Having defeated the Trooper, walk up the two sets of stairs. The Trooper on the right side is an optional fight.

Once you get to the top of the stairs, turn left to fight yet another Trooper.

After defeating the Trooper, continue along the linear path. This time, you will be challenged by an A.o.A Soldier.

The A.o.A Soldiers will use the same Digimon combination as the Troopers, but with an extra Tankmon.
Since they will be running three Digimon instead of two, be prepared to heal through Tankmon’s attacks at least once.
After defeating the first Soldier, continue to the door leading to the Master Room.
Heal your party before proceeding, as you will take on back-to-back fights. The first one will be the Soldier standing guard in front of the Master Room.

Once you get rid of the Soldier, an unidentified purple Digimon will walk out of the Master Room.

Vemmom Boss Fight
| Vemmon Details | |
|---|---|
| Elemental Weakness | None |
| Neutral Damage | Darkness, Fire, Ice, Machine, Thunder, Water, Wind |
| Elemental Resistance | None |
Vemmon is a Rookie Digimon, so this fight will only serve as a filler for the main story. Simply use your strongest moves and it will be over in no time.
After the fight, Vemmon will return to the Master Room.

You can continue to the left side of the building to fight another Soldier and a Trooper.
To advance the main story, enter the Master Room instead.
Master Room Puzzle
Inside the Master Room, you will have to solve a very simple puzzle to access the Game Master’s secret HQ.
To solve this puzzle you will have to form the word “MONSTER”.
Start by interacting with the pictures on the left side of the room. Move from the pictures on the bottom to the ones on the top.

After pressing the “N” switch, turn right and interact with the picture hidden behind the platform.

Next, move to the right side of the room. Again, start from the pictures on the bottom, then move to the ones on the top corner.

Once you complete the puzzle, the door to the Game Master’s HQ will open. As mentioned earlier, the game will proceed automatically from this point on.

A.o.A Headquarters
As soon as you enter, you will be stopped by three guards. They will only use a single Digimon.

| Guards Details | |||
|---|---|---|---|
| Digimon | Elemental Weaknesses | Neutral Damage | Elemental Resistances |
| Maildramon | Thunder, Water | Darkness, Wind | Fire, Ice, Machine |
Despite being a Mega-level Digimon, Maildramon is extremely weak. This one is a fraction stronger than the ones from the West Sector, but it still won’t be enough to pose a problem.
Just exploit its elemental weaknesses and Maildramon will go down in three or four hits.
After you are done dealing with the guards, you will take on the Game Master herself.

Game Master Boss Fight
| Game Master Details | |||
|---|---|---|---|
| Digimon | Elemental Weaknesses | Neutral Damage | Elemental Resistances |
| Minotarumon (Alt) | Fire | Darkness, Ice, Machine,Thunder, Water | Wind |
| Gargoylemon | Fire, Wind | Machine, Thunder, Water | Darkness, Ice |
| Persiamon | Fire | Darkness, Machine, Thunder, Water | Ice, Wind |
Her Minotarumon is stronger than the ones from the Protocol Ruins, with higher Defense and a higher Attack. Other than that, you won’t have to watch out for any special mechanics. Just heal through the damage as necessary.
The Game Master’s second Digimon is Gargoylemon. Just like Minotarumon, Gargoylemon doesn’t have any mechanics to watch out for. However, it will hit much harder, and also has a lot more HP.
Persiamon, on the other hand, can give you some trouble.
The Game Master’s ace Digimon will start the fight by casting its signature technique, Helter Skelter. This technique won’t deal any damage, but will instantly revert your Digimon back to its Rookie form.
Naturally, it will make you lose a full turn digivolving back to your Ultimate/Mega form.
Persiamon’s basic attack will hit four times, just like Datamon. Each hit will deal between 300 and 600 damage, which can easily lead to a KO. On top of that, Persiamon will occasionally move twice per turn, and also has a sizable HP pool.
Since Persiamon will be able to one-shot your party members, you should go on the offense. Do not waste time healing through the damage, and use Life Disks instead to get your KO’ed Digimon back in action.
Persiamon will go down in about five or six turns.
After the fight, Lisa will show up with Nick and Teddy to arrest the Game Master.

You will then learn some details about the A.o.A’s master plan. In order to foil it, you will need to access the Emergency Chamber in the North Sector.
However, the only way to get to the North Sector is by calling Digmon, which requires a DigiEgg of Knowledge.
And then comes the major problem:
The DigiEgg of Knowledge is an Amaterasu Server-exclusive item.
So next up you will have to jump right into the hornet’s nest – Amaterasu, the A.o.A’s home server.
