1️⃣ Navigate to the Hangar
After triggering the mine collapse sequence in Chapter 3, follow the only available path that leads to the hangar area.
⚠️ Combat Warning: 2 Crawlers will spawn along the way. Lure them into well-lit areas before engaging to conserve ammunition and health supplies.

3️⃣ Repair the Freight Elevator
Insert the spare fuse into the elevator panel and press the call button. The elevator will move to the middle level and stop with doors partially open.
- • Crouch and enter the elevator shaft through the partially open doors
- • Use the ladder to descend to the lower corridor level
- • Be prepared for potential enemy encounters in the lower areas
4️⃣ Locate the Storage Chest
Navigate through the lower corridor until you reach a door blocked by debris. Turn left into the adjacent tool room where you'll find the storage chest.
🔧 Required Tool: You'll need a crowbar (default attack key 6) to pry open the locked metal storage chest.
5️⃣ Retrieve the Blue Block Key
Use the crowbar to open the storage chest. Inside, you'll find the Blue Block Key accompanied by a notification sound. The key will be automatically added to your inventory. There's also an Energy Drink that respawns here - grab it to restore stamina.
6️⃣ Use the Blue Block Key
Return to the main corridor via the elevator and original path. Locate the blue block door and use the Blue Block Key to unlock it, granting access to the Maintenance Tunnels and continuing the story progression.

⚡ Alternative Route
Speedrun Strategy: If you've collected all hidden keys in previous chapters, you can obtain the Red Security Pass in Chapter 2 to bypass the blue door entirely. However, this approach causes you to miss two medical kits and important story recordings, so it's not recommended for first-time players who want the complete experience.

- • Save Frequently: The area has multiple enemy encounters and environmental hazards
- • Explore Thoroughly: Search side rooms for additional supplies and lore items
- • Listen Carefully: Audio cues often indicate enemy positions and upcoming threats
