Continuing the tradition of large and sprawling M7s. Quite a nice map with interesting ambushes, and can be quite punishing if you aren't sure how to handle them. Also, the missed items in the tally at the end is because I'm on v1.0; that's fixed in 1.1.
Doom: Sigil E5M7 - "Nightmare Underworld"
Sigil is a new megawad by Doom co-creator John Romero to celebrate Doom's 25th anniversary, taking its place alongside the original Ultimate Doom episodes as episode 5. It features nine brand new single-player/coop levels and nine deathmatch levels. I'm playing Sigil v1.0 (v1.1 is released at the time of uploading) on Ultra-Violence difficulty on the GZDoom source port.
