There is no interface, it's all sound. The biggest feature of "Listen" is that there is no screen display throughout the process, and everything is entered by the keyboard and mouse movement.Listen is a first-person shooter where the goal is to destroy all enemy units. Navigate the map with limited sound prompts and power-ups to find and destroy enemy units while battling them without being destroyed by them. Or play a 1v1 blind typing battle with friends, find each other's location in the map, and hide your location.
