Greetings, Citizens of Epsilon!

New Chapter: The Sewers Now Open! Sounds like celebration coming from the sewers in the Oldtown?! Lead your team to investigate and join the fishmen in their fest!

What's New

Sewer Chapter Content

  • After completing the first chapter and unlocking the sewer event, there will be a chance for sewer manholes to appear in specific chapters starting from your next mission.
  • You can enter the sewers multiple times in a single mission. After leaving the sewers in Chapter 1, you can re-enter through a manhole in Chapter 3, with clues carrying over.
  • The sewers feature three battles: a minor enemy fight, an elite enemy fight, and a boss fight.
  • All characters will have new dialogue scenes in the sewers.

18 new monsters (11 normal enemies, 4 elite enemies, 3 bosses)


Encounter "enthusiastically friendly" mutated monsters during the sewer festivities—each one is slimy, slippery, and has a distinct fishy smell...

8 New Environmental Units


More interactable objects can be picked up and pushed during battles! These might just turn the tide of the fight~

38 New Anomalities


The newly added anomalities are more diverse, and each one is now on A.R.A.'s "Do Not Touch" list!

5 New Factor


While exploring the sewers, you might encounter emergency situations that make you want to pinch your nose and run away... Besides that, be extra cautious when using fire.
WAIT......did I turned into a FISHMAN?!

8 New Events


The native inhabitants of the sewers have prepared a variety of exciting activities during the festivities—be sure not to miss them on your adventure!

New Special Elite Battle: Wealth Behemoth's Revenge


After smashing the piggy bank, there’s a 20% chance of triggering the "Piggy's Revenge" event.
After being shattered too many times, it seems Piggy’s patience has reached its limit...
