Abyss Echo

[GAMEPLAY CONCEPT & ATMOSPHERE] In the pitch-black void of the hadal trenches, light ceases to exist. Your eyes cannot guide you—only sound waves can reveal the abyss. "Abyss Echo: Sonar" is an innovative, atmospheric deep-sea exploration game powered by acoustic echolocation simulation. As the pilot of the "Echo-IV" scientific research submersible, you must navigate treacherous underwater chasms, volcanic hydrothermal vents, and uncharted trenches using phased-array sonar pulses to map bathymetric contours and salvage lost oceanographic data capsules. [KEY FEATURES & INNOVATIVE MECHANICS] ◆ Acoustic Echolocation Engine Total darkness surrounds your submersible. Emit standard spherical waves, focused directional ping beams, or deploy resonance decoys. Sound waves reflect off rock faces in real-time, casting glowing phosphorescent contours that decay over time. ◆ Realistic Ocean…
