Secrets[edit]

  1. Go to the eastern part of the map (right of the map start), next to the spinning tube with a cacodemon inside it. If you look at the walkway, you might spot a target switch on the stone wall. Shoot it to open a passage south of the cacodemon tube, where you can find ammo, health and a plasma rifle and energy cell packs, guarded by an ambush. (sector 1664)
  2. To get the soul sphere near the center of the map, climb and traverse the purple walkways to it. While doing so, look between the two spinning tubes with cacodemons inside them and shoot the target switch. The platforms near the steps will lower and you can claim the soul sphere. Look out for stealth alien troopers (on Ultra-Violence or higher) or zombiemen (on lower skill levels) when you attempt to take it, though. (sector 114)
  3. Drop off to the east from where the yellow key is to an area with a plasma rifle and boxes of rockets, along with a cyberdemon and an arachnotron. Notice the megasphere on a ledge in the center of this M-shaped walkway. The switch at the far end of this area lowers a teleporter, but also the megasphere as well. Run back to get it. (sector 475)

Trivia[edit]

  • In the comment section under the playthrough of this map on decino's YouTube channel, skillsaw shared the following information about this level:
"Some disconnected thoughts that I wasn't able to organize into a lucid paragraph:

- The title Xenoarboreum refers to the forest of synapse-like purple alien brain structures surrounding the void, which resembled trees to me. Later I was corrected and the title should have been Xenoarboretum. Oops.
- The earliest drafts of this map had a pure black sky and when I finally switched it to the synthwave neon gradient it really came alive. Plus stewboy's strange and unsettling (and alien) midi really works here.
- This map kicks off the final wing of Ancient Aliens, which I've always kind of imagined as being located at the center of the galaxy, though I never really convey that anywhere.
- That random off map green sphere has sectors joined with the one in actual map - it controls the height that those sectors move to. I copy pasted the original so I could easily tell which dummy sector was which.
- I could definitely have placed more MP monsters here!"
