Doom: The Dark Ages - Chapter 04 - Sentinel Barracks - Nightmare 150% speed - Instructional - HD/60

This is a commentary playthrough of Doom: The Dark Ages on Nightmare (M) settings, focusing on Chapter 4, "Sentinel Barracks" The Nightmare difficulty has adjusted settings for 150% speed, fast enemy projectiles, and Hard setting for Brink of Death. I'll be explaining the gameplay mechanics to new players and basic tactics and strategies for using the game's weapons, shield and melee weapons, along with recommended equipment upgrades. I'm not an "Ultra-Nightmare"-class/no-deaths player, but I have beaten the game on enhanced Nightmare difficulty and know enough to help you to get through it. This is Ultra Nightmare playthrough I used as a reference for my own game. Note the linked UN playthrough has no commentary    • DOOM: The Dark Ages - TRUE ULTRA-NIGHTMARE...   If the combat action in the video is too fast on 150% speed then you can slow my video down to 0.75 speed in the YouTube player to hopefully understand better what was happening. Chapter 4 Recommended upgrades (three, in order) 1. Shield 2 upgrade - Power Surge 2. Accelerator 2 upgrade - Modulator (chose from 2) 3. Accelerator 3 upgrade - Heat Blast (chose from 2) (uses 1 Ruby) Chapters/timestamps 00:00 Intro to the video 00:30 Modified Nightmare difficulty settings 01:30 Weapon and Shield upgrades so far 03:00 Start of the actual gameplay 03:27 Reviewing Challenges for Chapter 3 04:21 New Weapon - Skullcrusher Pulverizer 04:50 First arena combat of this mission 07:44 Battling our first armored Mancubus 08:47 Picking up gold and the first secret item 10:34 Intense Hell Knight arena battle 11:32 Battling more Hell Knights amongst barrels 12:35 Next big arena fight in a lower chamber 14:35 Locating another suit of armor 14:50 New Impaler weapon and tough cavern arena battle 18:16 Making upgrades at the Sentinel Shrine 20:15 Heading outside to structures on the cliffs 22:08 Third big arena battle on the cliffs 26:32 Secrets and completing the Prize Fighter challenge 27:45 MISTAKE - got too close to the Shield Soldier 29:43 Heading further down the cliffs, more Imp Stalkers 32:00 Warning about the Shield Soldier just ahead 33:30 More Shield Soldiers ahead!
