Its mechanics revolve around stealth, and the gameplay has been likened to that of Metal Gear Solid and Super Meat Boy.

The player controls a goggle-wearing clone who must make his way through a testing facility filled with hazards and robot sentries by staying in the shadows, risking instant death if he is spotted by an enemy.

The game was released on 4 November 2011 as Stealth Bastard as a free download for Microsoft Windows.

An expanded version, Stealth Bastard Deluxe, was released for Windows via Steam the following November.

It subsequently became available for OS X and Linux in April 2013 along with The Teleporter Chambers downloadable content released the previous month.
