Doom 3 Nightmare difficulty speedrun, map 7, 3 segments HD

Game: Doom 3 Difficulty: Nightmare Type of run: Segmented Map: Alpha Labs - Sector 3 Important: This is a heavily segmented run, many maps are split into several parts to make it possible to achieve optimal times. If you do not agree with this method of speedrunning do not watch any of my Doom 3 videos. This run is also in progress and has therefore not been verified by http://speeddemosarchive.com yet, however, according to the rules at http://speeddemosarchive.com there is no cheating in any of the videos.
