My first playthrough of Sigil II by John Romero (minus the secret level), enjoy!
This playthrough was done in GZDoom version 4.10.0.
You can pick up Sigil and Sigil II for yourself here: romero.com/sigil
*minor note I wasn't sure about during recording, Bethesda actually did put Sigil 2 in the add-ons of the Doom Unity sourceport, so you can totally play it that way as well :)
