Stifled is a Mic-Enabled Sound-Based Stealth Thriller, where sound is the only way you see and the enemies HEAR your fear. In Stifled, the sounds made by your in-game character and yourself through microphone input reveal the otherwise hidden world through ‘echolocation’. However, undue noise will attract the attention of creatures lurking in the darkness. To survive, you will have to tread the line between making sounds to see, and staying quiet to stay hidden.
