Other points of interest[edit]


  1. FinalNPC, MEGA secret (thing 324 via script 62 and "secret trigger" thing 2752)
  2. At the northwest portion of the map at the east side, use the button to open the side rooms and enter the shop. Use a weapon with splash damage to hit the southeast corner where a heart is to get a "hectic" secret. (thing 2340 via scripts 111 and 62 and "secret trigger" thing 2751)
  3. In the underwater tunnels near the north end of the mansion, make your way to the west side. There is a strange thingamajig somewhere at a dead end there, and picking it up removes some blockage in the tunnels. Head southeast from there all the way into an area you can crouch in and head south. In the next big room, swim up and northeast into another tunnel that leads to some unusual money in an "evil" secret. (linedef 481 via script 62 and "secret trigger" thing 2756)
  4. At the northwest end of the mansion where you can pick up two red cyclops, dive under the water and head west past where the door is, then into a room to the west. Surface at the northwest corner and follow the corridor with the "evil" secret to an MM Player. (linedef 6656 via script 62 and "secret trigger" thing 2755)
  5. At the northeast end of the mansion in the area with platforms over red liquid, get to the northeast side, then inch along the right wall going north to find a "good" secret with bombs. (linedef 9344 via script 62 and "secret trigger" thing 2754)
  6. At the southwest end of the mansion, there are bars that say that you need to find three power cores to remove the blockade. After finding these power cores, you can use the button behind the blockade for this "good" secret, opening a room to the south with allies. (linedef 12276 via script 62 and "secret trigger" thing 2689)
  7. South of the "skelly pit" are three holes. Enter the southernmost one and follow the passage to some bombs and a 75% health increase in a "good" secret. (linedef 12731 via script 62 and "secret trigger" thing 2715)
  8. At the northwest portion of the map, as you go through the thin, yellow corridors, one wall will say "Shh, it's a secret!" Use it, then head back to the rooms on the east side of the area (where you could get Secret #2). Head to the northeast room and crawl into the space there to get to an "evil" secret. The last room here contains tons of goodies to get. (linedef 12739 via script 62 and "secret trigger" thing 2632)
  9. When you get the message about getting three golden skulls, head to the large treasure room at the east end of the mansion. Head to the northernmost platform and jump north and into an opening. Follow the corridor of lips to a "hectic" secret where you must battle several insects. (linedef 13081 via script 62 and "secret trigger" thing 2695)
  10. At the north end of the mansion with a large mirror on the north wall, look to the right to find a high wall. To get this "evil" secret, you can use a weapon such as Monty's foot to hit behind the wall, crushing the heart on the other side and lowering the wall, allowing you to get a bomb and a maximum ammo increase. (linedef 13381 via script 62 and "secret trigger" thing 2690)
  11. When you get the message about getting three golden skulls, head to the north end of the mansion, to the higher tower, then onto the east part of the ledge. Jump north to the glowing wall and open it for a teleporter to a "hectic" secret which leads to a boss. (linedef 16349 via script 62 and "secret trigger" thing 2780)
  12. At the northernmost island in the map, go to the dock at the south end, face north, jump, and try to shoot the target in the distance. Doing so lowers several walls, including one with a totem pole pickup behind you which is an "evil" secret. (linedef 17628 via script 62 and "secret trigger" thing 2753)
  13. At the northernmost island in the map, at the southwest end, you can go through a waterfall to pick up bombs and a treasure chest in a "good" secret. (linedef 17712 via script 62 and "secret trigger" thing 2716)
  14. A room at the south end of the map has a single treasure chest in the middle and smoke billowing out the sides. If you head outside and look just to the southwest, you will spot a thin ledge. If you go on this ledge, you can get on the left side of the room where you can pick up some unusual money in a "good" secret. (linedef 17769 via script 62 and "secret trigger" thing 2699)
