Subsonic is a stealth-action puzzle game set in a 60s spytech world. Players assume the role of an agent of Subsonic Incorporated, a cohert mercenary contracting company that specializes in sound-based technology.
Agents of Subsonic Inc. wear sound-vision goggles and have a sound gun, which can be used to create remote distractions for guards, fire shockwaves that can shatter glass, or silence their footsteps.
The game's ultimate goal is for the payers to make their way to an objective, and make it out of the area without getting captured.
