Arcade Challenge’s Sealed Sector III 3-Star Guide

Leonard can be found in front of Herta’s Office as usual. For the third difficulty, your objective doesn’t change, but there’s no more helpful dialogue.

Tips so you don’t struggle in the boss fight like I did is to at least bring a physical, wind, or imaginary character. If you have Silver Wolf, you might not have to worry too much about the boss fight. You’ll be able to break the boss faster and mitigate big damage from his one-shot.

You’ll appear in the same map as the Sealed Sector II. Walk out of the room and follow the only path down. Cross the white bridge and head to the Control Device guarded by two Antimatter enemies. Flip the bridge to orange so you can cross over.

Go right and down to see your first Hacking Callcard. You can sneak scan it without aggroing the enemy, so you get your first buff when you fight him. Then head over to the next Control Device. Flip the bridge back to blue.

Cross the bridge and follow the path down until you can reach the “…” graffiti to unlock the door. Then go back to where you came from and you’re done with the first room.

Right after exiting this room, you’ll see a question mark graffiti. Investigate the graffiti and you’ll be teleported to the second room. Leonard will explain how this is a small-scale copy of Silver Wolf’s hacking that allowed her to transport the Antimatter Legions into the Space Station.

You’ll be able to see a boss blocking the way to the next room. Don’t fight him yet. Look to your left behind one of the display cases here. There’s a graffiti to weaken the boss that you can scan. This also where having a suitable element type like imaginary, wind, or physical makes the boss fight easier.

After beating the boss, you can now leave the room. Go straight when you see this intersection and turn left at the end. You’ll see another question mark graffiti. Investigate the graffiti. You’ll spawn to what would be the middle area of the Storage Zone.

I want you to look at the right side first. You’ll see your second Hacking Callcard and restore two of your Technique points here. After scanning the graffiti, keep looking to your right.

There will be two Antimatter Legion enemies. Can’t see it from here, but when you approach them, you’ll see they’re guarding a graffiti that’ll weaken the final big bad guy. Fight them and scan the weakening graffiti. With the current Hacking Callcard buff, you can oneshot them with the Simulated Universe: Silver Wolf attack.

Finally, right before the final boss, we’ll get our last Hacking Callcard. It’s right behind one of the pillars of the elevator here.

And you can finally fight the final boss here. With all the buffs and the graffiti to weaken him, it’ll be a breeze to fight. Having a lightning-type or imaginary-type character will help a lot with this boss battle as well! You will get 60 Stellar Jades here and on top of that, another 40 Stellar Jades by claiming from the Arcade Challenge.
