Cracking the Chapter 6 Roadblock: The Secret Bunker

Tarsier Studios has built a reputation for outmatching everyone in the "creepiness" department, and REANIMAL is their latest masterclass. While the sibling duo’s journey is largely a linear descent into nightmare fuel, Chapter 6: "Nobody Left Behind" throws a mechanical curveball at the beach bunker. If you’re hunting for the Platinum or just trying to survive the next encounter, the node terminal in this bunker is your primary obstacle. We’ve broken down the sequence to ensure you don't leave any collectibles—or your life—behind.

How to Unlock the "Secret Bunker" Trophy

Before you worry about progressing the story, you need to handle the missable content. There is a hidden poster collectible and a trophy tied to a specific node combination that most players will walk right past. Once you and your partner restore power via the external generator (found through the right-hand door), head to the terminal with the four nodes. To snag the Secret Bunker Trophy, input this sequence from left to right: Middle > Bottom > Bottom > Middle Pro Tip: For those wondering where this came from, the code was actually hidden in plain sight back in Chapter 1: "Dead in the Water," inscribed on a crate near the Clam Head mask. Pull the lever on the right after inputting this, grab your poster from the left terminal, and bank that achievement.

Solving the Main Progression Puzzle

With the trophy secured, you still need to get off the island. This requires an ammo airdrop to deal with the sea monster looming nearby. Our analysis shows that Tarsier has opted for a variable puzzle here—meaning the code for the ammo cache might differ between your playthrough and your friend's. To find the solution for your specific game instance:

• Scope it Out: Use the binoculars located by the window panel.
• Scan the Horizon: Focus on the edges of the "cannon island."
• Read the Crate: Look for a crate with a node combination written on it. This is your key.

Input that specific sequence into the terminal, pull the lever, and watch for the ammo cache to drop. This completes the bunker sequence and sets you up to take control of the massive cannon on the island.

Lead Tech Analyst’s Take

The bunker puzzle in REANIMAL is a classic Tarsier move—rewarding the "eagle-eyed" veteran who remembers a random crate from three hours prior while keeping the main path fresh with instanced codes. It’s a solid bit of puzzle design that prevents guides from becoming a simple "copy-paste" job for the main story progression. The game is currently sitting at a strong 81 on OpenCritic for a reason; it’s tight, it’s polished (running on Unreal Engine 5), and it doesn't hold your hand. If you’re pushing for that 100% completion, make sure you don't skip the Chapter 1 callback, or you’ll be backtracking through the nightmare sooner than you’d like.
