Tremor is the single map of Tremor: Part I - Genesis that requires a ZDoom-compatible port (even if PrBoom can run it with bugs). It was designed by Ross Mathieson (zarkyb) and uses a custom music track credited to DiluteCo.

The level received one of the 11th Annual Cacowards at Doomworld.

Other points of interest[edit]


  1. Walk north through the hallway near the entrance of the complex. As you approach a green armor that has a red target symbol on the ground around it (a baron of Hell will be here on Hurt Me Plenty or higher), drop into the nukage on the west and, inside the small tunnel, press on the misaligned wall (south) to find a soul sphere. (sector 664)
  2. In the room north of the yellow key room, go to the southwest corner where the wall opens up revealing shotgun guys. At the east end of their closet, open the wall to find a switch to use. After pressing it, go north, staying around the perimeter of this room, and in the west-east corridor at the north end of the room, one of the walls will be open. A megasphere and two backpacks are inside. (sector 3191)
  3. When you enter the room with the switch that lowers the yellow key, two pens with cacodemons open up. You can hop into the nukage to the south and press use on the pen to lower it. Ride this ledge up and open the tech wall on your right (west) for a soul sphere and a shout-out to Action Doom. (sector 710)
  4. One of the rooms to the south end of the map and west of the blue key room has a plasma gun in front of a switch. There is a switch on the backside of this switch as well. Press the backside of this switch, then take a lift up to the perimeter of the room. Go to the opening on the west side for a megaarmor and a switch. (sector 3194)
  5. Press the switch in Secret #4, then backtrack to the room just after the yellow door that you used to enter this part of the complex. There will be an opening to the north, functioning as a shortcut to the two sections of the base. (sector 3188)
  6. In the northwest corner of the blue key room, press on the northern wall next to the door to lower yourself behind the imp cage. You can find shotgun shells here. (sector 1281)
  7. At the nukage channel in the southeastern part of the map, just before the dropoff point, look at the lit walls on the east side. One of these walls is flickering. Open this particular wall to find a soul sphere. (sector 1678)
  8. In the large outdoor yard at the center of the map, you should spot a megaarmor on top of the southwest pillar. To reach it, look towards the W-shape on the wall which is composed of hexagonal gray metal walls. While facing this W, press on its right side (south) to find a teleporter, which transports you on top of the megaarmor. (sector 3034)
  9. North of where the blue key is located, you can spot a rocket launcher and some rockets. To reach this area, go northwest from the blue key room and take the stairs east of the door that leads to the large outdoor yard. Open a brown wall on your right (south) as you ascend the steps to reach the rocket launcher. (sector 1241)
  10. You can enter the courtyard in the northeast part of the map by opening the wall in between the two windows. Several supplies are outside, including the BFG9000. (sector 2798)
  11. Inside the room just northeast of the large outdoor yard at the center of the map, go onto the brown-floored area that has two computer terminals. There are three steps leading back up. Press the wall near the middle step to open a passage to a backpack. (sector 2223)
