Comprehensive Guide to Survival in Debris (Moonray Studios)

Debris is an atmospheric underwater adventure game where players, as Ryan, must navigate treacherous deep-sea environments after being trapped by collapsed ice and rock. The game combines exploration with elements of action and a strong emphasis on mental struggle and developing psychosis. Survival hinges on careful resource management, strategic combat, and understanding the unique challenges of the deep-sea setting.

Understanding Core Mechanics: Power and Movement

Your survival suit and the Squid ROV companion operate on a finite power supply, which acts as your life source (oxygen, heat, pressurization). When this energy reaches zero, Ryan succumbs to the environment.

  • Power Management is Key: Constantly monitor your power level. Replenishing power requires harvesting glowing orange 'Debris' deposits found throughout the game world. Maximizing collected Debris is crucial for survival, as your suit and Squid can store up to 75 minutes of power.
  • Movement Limitations: The game features basic movement controls (four directions, rise, fall) without sprint or dodge mechanics. This design emphasizes a sense of powerlessness and requires players to think strategically about their path and engagements. Following currents can sometimes aid navigation.

    • Essential Tools: Flares and Spears

    You are equipped with a 'Tool' that has two modes: shooting flares or spears. Both consume power, so their use must be strategic.

  • Flares: Cost 1 minute of power per shot. Flares are useful for lighting up dark areas and can be used to de-aggro sharks completely. They are also key for triggering certain enemy behaviors without direct engagement, such as with Bobbit worms.
  • Spears: Cost 3 minutes of power per shot. Spears are primarily for eliminating enemies. Guardians, for instance, may require two shots.
  • Strategic Use: Evaluate whether the power cost of using a tool outweighs the benefit. For example, if an energy grove is guarded, the energy gained from harvesting should ideally exceed the power spent to clear the guards.

    • Navigating Hazards and Combat Strategies

    The deep-sea environment is fraught with various hostile creatures and obstacles. Understanding enemy patterns and using your tools effectively is vital.

  • Bobbit Worms: These worms attack from the ground or walls. A good strategy is to trigger their attack with a flare, wait a few seconds for them to retreat, and then move forward. Rushing too soon or waiting too long can result in taking damage. Some sections, like the Bobbit lair in Chapter 8, are dense with them and require moving along routes with the lowest concentration.
  • Sharks (Light and Teeth): In Chapter 7, sharks are a threat. Flares can be used to de-aggro them entirely.
  • Glowing Fish: Found in chapters like 5 and 11, these fish deal damage (10 MP) on contact. They can often be moved by shooting them with spears. Avoid huge fish that cannot be killed by staying clear of them, as they won't track you unless you get too close.
  • Worms and Dark Fish Delta: Certain sections, like those with worms in Chapter 8 or the dark fish delta, require navigating without taking damage for specific achievements. Detailed strategies for these are available in comprehensive walkthroughs.
  • Flare Eaters: These enemies can attack from behind, so ensure an area is clear before proceeding.

    • Managing Your Companion: Sonya

    Your ROV companion, Sonya, is crucial for harvesting Debris, but her AI can sometimes be a hindrance.

  • Call Sonya: If Sonya lags behind or wanders off, you can call her to your location by pressing 'Q'. This is important to ensure she harvests Debris and stays close, as running out of power for either you or Sonya results in a game over.
  • Sonya's Behavior: Be aware that Sonya may sometimes make poor decisions, such as rushing into guarded areas or attempting to harvest unneeded energy, potentially putting both of you in danger. This can undermine strategic play and lead to unnecessary damage.

    • Exploration and Collectibles

    Exploration is a core component of Debris, with several collectibles and secrets to uncover.

  • Montipora Logs: These are secret collectibles found throughout the cave network. There are 24 Montipora logs to find across all playthroughs, with achievements tied to finding specific numbers in one delusion (playthrough) and completing the entire archive.
  • Secret Locations: Look for hidden areas like the Hall of Voices (Chapter 8) or secret irradiated montipora to dive into ALTA's archives. Maps in detailed walkthroughs can pinpoint these locations.
  • Scenic Screenshot Mode: Press 'H' multiple times to remove the HUD and enable scenic screenshot mode, useful for capturing the game's atmosphere.

    • Achievement Hunting Tips

    Many of Debris's achievements are missable and often require multiple playthroughs (at least four, more realistically five for a first-time player without guides).

  • Categories: Achievements fall into Exploration, Danger, Montipora Logs, and Ending categories.
  • No-Damage Runs: Several achievements require making it through specific sections without taking damage, such as areas with worms, dark fish delta, glowing fish, or sharks. These often require precise movement and strategic use of flares/spears.
  • Specific Actions: Achievements like 'Jacques Cousteau' (shooting a flare towards fish in Chapter 3) or 'Over Here, Sonya!' (finding a frozen fish in Chapter 6) require performing specific actions at certain points.
  • Montipora Completion: To unlock all Montipora-related achievements, you'll need to find all 24 Montipora logs across different playthroughs.
  • Unmissable Achievements: Some achievements, like 'Thrusters Disabled' and 'Thrusters Enabled', are tied to story choices in Chapters 6 and 8 and are unmissable.
