  • More Creature Encounters – Added additional creatures to keep the tension high.

  • New Submarine Mechanic – In 2-Player Mode, the player in the sub can now fire missiles to blast through rock walls, opening up new paths.

  • UI & Control Updates – The submarine HUD and controls have been reworked for clarity and smoother gameplay.Chapter 10 – Quality of Life Upgrade

Goal: Improve overall flow and reduce frustration.

  • Less Falling Debris – Rock and debris drops have been reduced by 40%, giving you more breathing room.

  • Missile Mechanic Added – Just like Chapter 9, the submarine can now blast rock walls to help you push forward.

  • UI & Control Updates – Same submarine updates carried over for consistency.

We Hear You
