Halden Deep has gone dark.

You are Mara Voss, a night technician at an underground sound research lab. Experiment ECHO has failed. The power is out, the staff are gone, and something blind is walking the halls, hunting by sound.

Send out a sonar pulse and the world lights up for a heartbeat. Walls, doorways, the shape of the room. But every pulse is a sound, and sound is how it finds you.

FEATURES

  • See with sound. The facility is pitch black until your pulse sweeps through it.
  • Two-way sonar. The hunter pulses too. If its ring reaches you with nothing in between, it knows exactly where you are. Hear the wind-up and get behind a wall.
  • Four floors of an abandoned lab, each adding something new: noise makers, Sentinels that shriek for the hunter, flickering power, and a final chase in The Well.
  • A story told in tapes. Dr. Varga guides you over the radio. The tapes you find say she isn't telling you everything. Two endings.
  • Open Mic mode (optional). Turn on your microphone and the monsters hear you. Talk, laugh or scream and they come running.
  • Hiding lockers, a limited pulse battery, upgrades between floors, checkpoints, three difficulties and 3D sound. Play with headphones.
  • Accessibility captions with direction arrows, so the game is playable with the sound off.
