Hey everyone, welcome to Zone 400, the sequel to Zone 300 which I let's played in 2022 almost 2 years back, and now it's time for it's sequel. So, What is Zone 400?! Zone 400 is a 33-map megawad created by Paul Corfiatis for Doom II. It was first released in July 2021, with the final release in September. It is the sequel to his 2013 megawad Zone 300, which had a linedef limit of 300 per map. This time the limit was increased to 400 per map, except on MAP32 and MAP33. As is his custom, Corfiatis composed all of the music. It received an honorable mention at the 2021 Cacowards. This will be coinciding with my Plutonia Experiment (100%) Walkthrough. This is again played on the "Ultra-Violence" Difficulty with getting a 100% of Kills, Secrets, and Items. This is Map01: Coombe.
