LIVE: PSX Doom I CE - Ultra-Nightmare Campaign and its Lost Levels - 100% Secrets

[Youtube Reupload] Go check my PSX Doom II CE - Ultra-Nightmare too! https://tinyurl.com/35zcxr22

Had fun! Secrets are getting settled in my memory now. There was just a couple that had weird floor triggers. E4M1 was really weird, it did not have the NIN logo like on the PC version, so not sure where the trigger was and could only make it work using IDCLIP.
Getting 200-to-0 by the crusher in E4M7 was the biggest disappointment.
