After unlocking Avalon Fortress, you can start collecting fragments of the City of Steam map. Once all the fragments have been collected, the map may be purchased for 70 gems.

Complete this maze to get the Zeros gumball.

Hidden GumballEdit

To get the Future Cat Gumball:

  • You need Adventurer on your team as leader or soul link.
  • You will meet Future Cat on an early floor <65. Make a note as he will remain on that floor for that particular dungeon run.
  • After you meet him, you will find his Parts (A, B, C, D) inside Steam Tanks, Steam Airships, or corpses. If you don't find the parts by floor 60, use Portal of Earth to return to earlier floors.
    Part A = Future Cat quest start
    Part B & C = Steel Cabinets in Airships/Tanks/Guard Rooms. Both Spawn together.
    Part D = Researcher's Remains.
  • The fifth part (E) can only come from a Gumball Villager (thus the need for Adventurer.)
  • Combine all Parts into Future Cat's Dynamic Device (top right corner of Mechanics Page, but does not require chips.)
  • Return to the floor where you originally met Future Cat (via Portal of Earth)
  • Give Future Cat the crafted item Future Cat's Dynamic System and he will join your team / give you fragments

Out of Maze LootEdit

Get these items in the maze or by raiding:

Raid only:

Title specific lootsEdit

For items available here through the God of Thieves title, see here.

For souls available here using the Farplane's Bow and Farplane Arrow, see here.


  1. With God of thieves, you can encounter a locked safe. Code is 654321. It drops 3 gems the first few times. After that it drops 10000 coins.
  2. Useful Potion: Voyager or Cactus or Great Designer (if you have it)
  3. There are five airship Robots available in this maze:
  4. Zap means to find a damaged core within a tank and have it explode (destroy a Steam Airship or Steam Tank with your airship before entering). This is fairly rare and won't work every time.
  5. To complete the DP Quest - "Don't enhance Engineering Manual to Level 50" you must not upgrade your manual until you reach floor 50. Using machine-type gumball will upgrade your manual automatically. Thus, the quest will fail as you reach floor 50. If you are using machine-type gumball, DO NOT pick up the manual from the Researcher's remain, then you will be able to complete the quest at floor 50.
    Neither try to craft the Future Cat item from the manual, do it after you complete this DP quest.
  6. To complete the DP Quest - "Watch TV programs to upgrade Engineering Manual 0/5" do as follows:
    • Step 1 - Find a floor that has a tv room. Enter and kill all the mobs inside, watch the tv and if you get an upgrade, you are done. Otherwise, please proceed to the next step.
    • Step 2 - S/L the game (NOT S/L 30). Re-enter the room, DO NOT kill the mobs inside and EXIT.
    • Step 3 - PAUSE the game. (Be careful not to pause the game if you already kill the mobs inside, otherwise this trick will not work)
    • Step 4 - When you continue, re-enter the room and kill the mobs inside, if you get an upgrade then you are done. Otherwise, repeat step 2 -4.
