This is indeed Unspeakable Persecution, as the demons really hate it when we go against their unholy ruler. This map also gets really dark in one section, which will make it harder to see, but there's is two weapons that we've been waiting for here as well.

This is a playthrough of the fifth episode of Doom called SIGIL (or SI6IL), which was made by the legendary John Romero. This new episode consists of 9 new maps made for The Ultimate Doom, and they are also vanilla-compatible. I played this WAD on ZDoom with the “Ultra-Violence” skill level. The game footage was recorded with Fraps, as the video was made with Windows Movie Maker 2012.

IMPORTANT NOTE: As the title implies, the version I played in this video playthrough series is version 1.21, and it is subject to change in the future with new versions.
