MAP24: Culture Shock is the twenty-fourth map of Ancient Aliens. It was designed by Chris Kassap (lupinx-Kassman), with extensive additions by Paul DeBruyne (skillsaw) (→see trivia section), and uses the music track "Imaginarium," composed by Stuart Rynn (stewboy). The par time is 7:00.

Culture Shock was featured in Doomworld's Top 100 Most Memorable Maps, placing 5th.

Other points of interest[edit]


  1. In the first area, the switch in the garden closest to the rocket launcher opens up the cage with the super shotgun inside. Quickly run here to get it as well as stimpacks, a backpack, and shotgun shells. (sector 885)
  2. Open the red door and you should spot a target switch past the cage on the right. Shoot it and turn around towards the rope that's now available. You will wind up in a small bedroom with energy cell packs and a stimpack, as well as an armor and plasma rifle (but only on Hurt Me Plenty or higher). (sector 2407)
  3. In the first area, you may notice that one of the switches in one of the gardens requires the yellow key. Make your way to the area where the yellow key is located. When you do, turn around and climb up the tower that you previously climbed to open access to the yellow key. The top of this area had yellow bars before, but they should be gone now. From there, just backtrack all the way until you reach the yellow switch from before. This opens up a blocked tunnel near the rocket launcher. You will wind up in a dark room, where as you move forward, messages appear on the floor. Follow them to a room with a switch, and you will free the person from the nearby cage and claim a medikit and energy cell packs. More importantly, head south and the southeast corner has a BFG9000 and a teleporter back. (sector 3059)


At the red skull area, the switch lowers the red skull as well as a white block with a revenant inside, both for 10 seconds. If you stand inside this block as it rises, you will be unable to get out.

The maximum number of items you can receive for this map is 92%, as three health bonuses (things 616, 619 and 620) are unobtainable.

The button at the start consists of two linedefs meant to be pressed simultaneously, but one can be pressed independently by pressing the sides touching the button, lowering only parts of the teleporter railings.

The silent teleport transitions in the yellow key tower's stairwell are all placed correctly except for those at the highest point in the tower, meaning you can walk backwards immediately after entering it and bump into a black wall.

Technical information[edit]

Inspiration and development[edit]


  • After the map got onto the Top 100 Most Memorable Maps list, Chris Kassap wrote a forum post which reveals the backstory behind the location in the map, as well as a few development trivia.
  • The TV in secret #2 shows the Tarkus from the 1971 Emerson, Lake & Palmer album of that name.
  • In the comment section under the playthrough of this map on decino's YouTube channel, skillsaw commented on this level as follows:
"This map is amazing. Kassman has the tendency to make awesome maps in bigger projects that steal the show (CC4, TNT2, and here).

I think the title Culture Shock refers to the mishmash of different textures that appear on the map - Mayan, Incan, Egyptian, and Arabian, and perhaps some others. Kassman kind of expands here on the worldbuilding in the first episode, where American and Egyptian ruins are kind of fused together.

The archvile [sic] fight probably feels a bit weird in comparison to the rest of the map, since it's a part of the map that I made - for better or worse, I had a deadline set for submissions because I wanted to release the project before I moved to a new city - and I ended up helping to get this map done in time by making a few small areas to tie the map together, including that AV fight."

  • Chris Kassap (lupinx-Kassman) replied to skillsaw's comment under decino's playthrough of the map, sharing the following information about this level:
"(...)Huge thanks to Skillsaw for helping me finish the map so it could be included, and for giving me the opportunity to be a part of this awesome project. The path beginning at the red key door and ending at the first exit teleporter before the arena were all Skillsaw in fact. It's also why these areas offer the best gameplay experience haha.

I went through several scrapped map ideas before finally deciding on the "ruins in the clouds" theme. Amusingly I didn't settle on that idea until about 3 weeks before the deadline IIRC, but I started the map over for it.

The RC1 version of the map did not have the saucer intro, the gateway of knowledge outtro, nor the TV and prison secrets. I added the intro and outtro in later versions to help tie it thematically with the rest of the megawad. The intro is a flying saucer like the rest of the saucers you see throughout Ancient Aliens (the purple coloration was chosen purposely to match the saucer colors at the end of MAP23). Ancient Aliens' flavor text "Go on a journey to discover the truth about the enigmatic origins of human civilization..." in the description, as well as the MAP29/MAP30 combo, are what inspired me to come up with the Gateway of Knowledge. The idea being that it is a door to the burning question in your heart. Not necessarily the question you think you have. It could be something buried deep in your subconscious. Most users of the gate come away traumatized. Knowledge isn't always worth the price of admission. In the player's case, it ultimately leads them to the truth they discover in MAP29.

The prison secret contains one of the reoccuring characters I created for my maps. The prisoner is named "GreyNote" (or just GN) after my favorite Necros song. These characters are part of a breadcrumb trail that links most of my maps together. Versions of them also appear in Autumn Flock, the independent game I've been working on for a while."
