Silent Hunter is an audio game made in 2013 Global Game Jam at the site of NYU Game Center, winning the Best Audio Design and nominated for Best Use of The Theme.
The game is for two players. One acts as the hunter and the other the prey. The hunter tries to catch the prey as fast as possible while the prey tries to survive as long as she can. The players can see nothing but the frequency and volume of the sounds of heartbeats and breath could tell the players how close they are. Can be played as a party game for audience in Spectator Mod, in which the players are required to blind themselves from the screen while all the audience can watch.
The game can be downloaded here (Windows Only).
