Bastion of Chaos is a single-level PK3 for Doom II and the GZDoom source port that came out in July 2020. It was designed by Bridgeburner56 and uses the music track "The Coming Hour" by John Weekley (PRIMEVAL). It won a Cacoward that year, and the song was distinguished as an Odyssey of Noises.

Bastion of Chaos is a very large slaughter map using OTEX textures and advanced lighting effects of GZDoom. The level is available in a full edition requiring a comparatively powerful computer, as well as a low spec edition for modest systems.

Other points of interest[edit]


  1. At the southwest part of the southern section of the map, an alcove above has a megaarmor. To reach it, head to the fenced-in section to the east and towards the switch, then press on the recessed wall to find a teleporter that leads you straight there. (sector 18388)
  2. In the northeast section of the map, go to the area with the super shotgun, then head west and northwest from there, into the blood, to get a soul sphere. (sector 22841)
  3. In the outside area southeast of the starting point, go to the pedestal with the megasphere and look south. A candle marks the beginning of some small steps leading down to a soul sphere. Be careful not to fall as you get it. (sector 23448)
  4. In the yellow key hub, head towards the northwest steps and go a bit north from the base of these steps to find an eye switch. After using it, quickly head to the northeast steps and into the alcove northwest from them to get a megasphere. (sector 23779)
  5. At the northwest section of the map, use the lift that has a single backpack, then at the top, jump to the west to reach the blood. Follow the candles to get a soul sphere. (sector 23781)
  6. In the western section with the spiral staircase and rocket launcher (west of the hub), go to the south side of the starting platform and gently drop down to pick up a backpack and energy cell packs. (sector 23786)
  7. In the yellow key hub, go towards the northeast teleporter. Just past it, there is an eye switch tucked in the wall. Use it, then head south of the teleporter to find a rocket launcher and a box of rockets in a small alcove. (sector 32351, 19526 in low spec ed.)
  8. In the southern hall at the southern section of the map, head past the north switch, into the blood, and head east. There will be an alcove to the south that leads to a hidden megasphere. (sector 32358, 19529 in low spec ed.)
  9. At the east end of the southern section of the map, go all the way south to the switch, then into the blood pool to the west of it. You will find a small alcove with energy cell packs here. (sector 32370, 19342 in low spec ed.)
