London studio Somethin' Else has built its game-making reputation on making audio-only titles, notably the Papa Sangre series.

At Pocket Gamer Connects London 2015, gameplay designer Antoine Pastor spoke about the company's first-person zombie shooter Audio Defence - Zombie Arena.

Like previous titles, it relies almost totally on audio cues, reducing the game's graphics to user interface elements.
