Inspiration and development[edit]


  • In the comment section under the playthrough of this map on decino's YouTube channel, skillsaw shared the following information about this level:
"Weird, I'm not sure why I didn't add more MP monsters in the final map. A late wave of Archviles [sic] or maybe some extra roaming cybers [sic] could have been fun. It could definitely have used them.

Anyways, I'm glad you played these two final maps together - the most important thing for me about ending Ancient Aliens was closing out the story with all the silly plot twists. I didn't really want to do another Valiant-style boss - instead, I wanted the wad to be memorable for something other than it's combat."
