Introduction to Debris's Secrets

Debris is an atmospheric underwater adventure game that blends exploration with action and psychological themes. As Ryan, a videographer stranded in the Arctic depths, players must navigate treacherous environments with their AI companion Sonya and a drone called Squid. Beyond the main objective of survival, the game features several hidden secrets, collectibles, and challenging achievements that encourage thorough exploration and mastery of its mechanics. Achieving 100% completion typically requires at least four playthroughs, as many achievements are missable and tied to different 'delusions' or realities within the game.

Montipora Logs: The Core Collectible

One of the primary hidden secrets in Debris revolves around the collection of Montipora Logs. These serve as key collectibles that deepen the game's lore and contribute significantly to achievement progression. There are a total of 24 Montipora Logs scattered throughout the expansive cave network.
  • Finding All Montipora in a Delusion: An achievement is awarded for collecting at least 12 Montipora in a single playthrough (referred to as a 'delusion'), and another for finding all 24.
  • The Hardest Achievement: To truly complete the Montipora archive, players must find ALL Montipora across ALL four delusions. This necessitates finishing the game four times, each with a different delusion, as the content of the Montipora logs can change based on your current delusion's state. Until the first branching choice in Chapter 6, all Montipora logs remain consistent.
  • Secret Irradiated Montipora: A specific secret involves finding an 'irradiated montipora' which grants access to ALTA's archives, providing deeper insights into the game's narrative.
  • Secret Locations

    Specific hidden areas offer unique discoveries or contribute to achievements:
  • The Hall of Voices: Located in Chapter 8, titled "Fear," this secret area is crucial for an achievement. To find it, players must navigate to the right side of the final chamber before the exit and explore through the bottom of the glaciers. A mound of blue coral indicates its precise location.
  • Hidden Achievement Challenges

    Several achievements are tied to specific, often challenging, gameplay feats that can be considered 'hidden secrets' of execution:
  • No Damage Sections: Mastering certain hazardous areas without taking any damage unlocks achievements:
  • * Dark Fish Delta (Dark): Complete the section with glowing fish in Chapter 5 without taking damage. Spears can be used to move them if necessary. * Light and Teeth (Sharks): Successfully navigate the section with sharks in Chapter 7 without taking damage. In-depth strategy is often required for this. * Bobbit Lair (Worms): Survive the Bobbit worm lair in Chapter 8 without taking damage. This chapter is noted as being very intensive and the hardest in the game, with bobbit worms attacking from the ground in huge numbers. * Dark Fish Delta (Flow): Get through the section with glowing fish in Chapter 11 without taking damage, again using spears to move them as needed.
  • Exploration-Based Discoveries:
  • * "Choking Hazard" (Dead Fish): Find the dead fish that consumed an urchin in Chapter 9. * "Over Here, Sonya!" (Frozen Fish): Discover the frozen fish in Chapter 6.
  • Interactive Secrets:
  • * "Videographer" Achievement: This is unlocked by enabling the scenic screenshot mode, which can be done by pressing the 'H' key multiple times to completely remove the HUD. * "Jacques Cousteau" Achievement: To achieve this, make your presence known in the "Shock" area by shooting a flare towards the fish in Chapter 3.

    General Exploration Tips for Secrets

  • Resource Management: Power is critical for survival and using your tools (flares and spears). Flares consume 1 minute of power, while spears consume 3 minutes. Always collect 'Debris' to recharge your suit and the Squid drone, which has a maximum capacity of 75 minutes of power.
  • Map Consultation: Frequently consult your map, especially in areas with strong currents or tricky collectible locations. Currents can pull you past lightly hidden areas, making it impossible to backtrack for missed items like Montipora.
  • Multiple Playthroughs: Given the emphasis on different 'delusions' and missable achievements, multiple playthroughs are essential to uncover all secrets and achieve 100% completion. The game can be speed-run in 2-3 hours once familiar with the layout.
  • Listen to Dialogue: Pay attention to the dialogue between Ryan and Sonya, as it often provides hints about the environment, threats, and the overarching mystery of ALTA's agenda.
  • Environmental Cues: The game relies heavily on atmosphere, with darkness and sound design creating tension. Keep an eye out for subtle environmental cues that might indicate hidden paths or points of interest.
  • By following these tips and actively seeking out the specific hidden elements, players can fully immerse themselves in the mysteries of Debris and uncover all its secrets. Good luck, diver.
