Bricktonite Showdown

Talk to Uber Woman again to get this quest. You have to clear the designated areas of Omega goons. They will appear in fixed numbers but not all at the same time. After clearing the area, head to the next ones and repeat the process. Once clear, you have to enter the Infernal Fortress hideout.

Head to the next large hall and fight all the enemies down to the last brick. You don't need to explore that much in this hideout; after defeating all enemies, all other doors will unlock, leading to the chests and the doorway to the next area.

In the next area, you'll find Uber Woman. Talk to her then go to the next room where you have to face Crystalozor for real. Use ranged attacks and run around it. Its attacks can be easily avoided and you shouldn't have problems dealing with it at this point.

After defeating it, access the computer ahead to complete the hideout. Talk to Knight Rat to complete the quest. Now you have to clear the remaining hideouts.
