Sentinel Command Station, the twelfth mission in Doom: The Dark Ages, challenges players to locate three distinct collectible types scattered throughout the level. These valuable items include codex entries that expand the game’s narrative, cosmetic weapon skins for personalization, and collectible toys representing various in-game entities. Understanding the built-in tracking system is crucial – the map screen displays your total collectible count and automatically updates as you discover each item, providing real-time progress monitoring.

Collectible 1 - Sentinel Command Station Codex

Immediately after descending from the ventilation shafts at the mission’s commencement, navigate carefully through the initial corridor. Rather than proceeding left as the main path suggests, immediately veer right into a concealed cavern illuminated by a central fire pit. This early diversion is easily missed if you’re rushing through the level – the codex page rests conspicuously against the rear wall of this hidden chamber.

Pro Tip: Many players overlook this collectible because they follow the obvious path forward. Always explore alternative routes in the first major area of any level to avoid missing early-game treasures.

Collectible 2 - Nightmare Chainshot Skin

During the early stage progression, you’ll access the command center where the game directs you to leap over an exterior ledge. Before making that jump, thoroughly scan the chamber’s perimeter for a destructible wooden barrier. Execute a powerful shield bash attack to demolish this false wall, revealing a concealed compartment. Inside this secret area, ascend the platform to claim the Nightmare Chainshot weapon skin.

Common Mistake: Players often miss this collectible because they immediately follow the objective marker to jump down. Always complete environmental scans before progressing to new areas. For more weapon customization options, check our Weapons Unlock guide for advanced strategies.

Secret Key Location
Collectible 3 - Kreed Maykr Toy

Progress through the mission until you acquire the Auto Turret Rune ability. Upon obtaining this power-up, immediately pivot 180 degrees – a launch mechanism will propel you back through the ventilation shaft you previously descended. Locate the platform featuring a golden chest, then identify the opposite wall that permits dash penetration. Navigate through this newly accessible vent system into an isolated chamber containing the essential secret key.

Proceed to the central plaza dominated by a massive statue, then enter the adjacent room housing an upgrade altar. This chamber conceals a locked compartment requiring the secret key; the Kreed Maykr toy rests just inside this secured area. Understanding class abilities can enhance your collection efficiency – learn more in our Class Guide for optimal character builds.

Efficiency Strategies: Complete collectible hunting during your initial playthrough to avoid repetitive backtracking. The map tracker shows collected items but doesn’t provide location hints, making systematic exploration essential. Weapon skins like the Nightmare Chainshot provide visual customization without statistical advantages.

Avoidable Errors: The most frequent mistake involves rushing through objectives without environmental scanning. The wooden wall in the command center blends seamlessly with the surroundings, requiring careful inspection. Additionally, many players forget to backtrack after obtaining the Auto Turret Rune, missing the secret key entirely.

Advanced Technique: For speedrunners, the entire collection process can be completed in under 5 minutes with precise route optimization and advanced movement techniques.

Action Checklist

  • At mission start, turn right into fire-lit cave for codex entry
  • Before jumping from command center, shield bash wooden wall for weapon skin
  • After Auto Turret Rune, backtrack through launcher to find secret key
  • Use secret key on locked room near upgrade shrine for Kreed Maykr toy
