MAP10: Atlantis Rising is the tenth map of Community Chest 3. It appears to take place in a water treatment facility. It was designed by Will Hackney, and uses the music track "Nothing So Cruel" by Mark Klem from Memento Mori II MAP19: The Shaft. Permission was granted by Klem for Hackney to use the track.

In spite of using colored keycard borders around certain doors, the level does not contain any keys; to progress through the level, the player must find switches marked with each of the three keycard colors to open doors marked with the same color. The level is also more noticeably cramped than in other levels in the megawad, sometimes to the extent of hindering movement.

Other points of interest[edit]



  1. Near the red switch, there is a portion of the metal wall near the blue wire, marked with a lightning bolt. Open it to find a ladder leading up to a rocket, a box of rockets, and a rocket launcher. (sector 127) There is a switch in this room that will open the western door, should you accidentally dip back into the hall before it closes.
  2. While jumping across the metal platforms at the east, jump from the penultimate platform toward the southeastern corner of the last platform. You will land on a medikit, a box of shells, and a backpack. (sector 861) You may also reach this secret while below the platforms by straferunning at it from the south, although it may take a few tries before you pull it off.
  3. In the southeastern tunnel in the middle of the reservoir, there is a waterfall near the entrance, with an opening at the top. After filling the reservoir twice, go back to where this waterfall was to find that you can now enter the opening, leading to an elevator. (sector 571) Take the elevator up to obtain a megaarmor, two energy cell packs, and a plasma gun.
  4. To the northeast of the boat is a tiny recess within the wall. Press on it, and it will open into a stairway. At the top of the stairs, edge your way across the ledge, and head through the gap in the streams of water to get a BFG9000. (sector 1135) This may take multiple tries; the ledge is very small, and the Doomguy's occasional elasticity can cause you to bounce off the water streams as you try to get in. Heading through the gap may also take a bit of time due to the little amount of space you are given to do so. This secret also houses the switch to non-official secret #2.


  1. In the room with the two alternating pistons, ride up to the top of the platform. Look to the north, just below the ceiling, and you will see an open "electrical box". Inside is a red button. Shoot the button (use the shotgun for the wider spread), and a supercharge will rise out of one of the pipes (sector 445) at the edge of the platform.
  2. Next to the BFG in normal secret #4 is a computer panel with exposed circuitry; press it to lower a wall in the east leading back to the start of the level. Going through this wall causes a supercharge to appear next to where the first armor was found.
  3. The east water control switch in the far north (linedef 2277) drains the northeast reservoir with the metal blades. This deposits a megaarmor (thing 404) in this reservoir, likely leaving it more exposed than intended due to a bug described in the Bugs section.


Both megaarmors descend and get their bounding boxes snagged on ledges, making them appear to float in the air unless playing with item sliding like that offered by MBF. The megaarmor of non-official secret #3 is also visible through the ceiling before activation when playing with software rendering mode.

There are switches with trigger lines in front of without the pass use flag, making them block use attempts until the player is closer to the switches than normally required. The most noticeable cases are trigger linedefs 2359 and 2277.

A medikit (thing 237) starts floating by the time it becomes reachable.
