Alexa received accolades for her work in GZDoom - Shadows of the Nightmare Realm in 2017 and, more recently, 2018's Umbra of Fate - but she has had a lot of prior practice in Doom editing utilities. Much of it went toward her incomplete one woman megaWAD (Kill) but her advanced source port debut was in the Doomsday engine with One Doomed Marine in 2010. I'm pretty sure that Jaakko's .EXE was my first community port since it was the target for Kaiser's D64: Absolution TC. It looked a bit different back then, though, and the gap between this five map minisode's original release (made for v1.8.6) and the current version of Doomsday (v2.1) has introduced a number of complications in its functionality.
