Stealth Bastard Deluxe: Tactical Espionage Arsehole is a 2D platform video game developed and published by Curve Studios. 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 first 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 Ubuntu in April 2013 along with The Teleporter Chambers DLC released the previous month. In June 2013, it was released for Android as part of the Humble Bundle with Android 6, including DRM-free versions for Windows, Mac OS and Ubuntu and its soundtrack. Versions are also planned for the PlayStation 3 and PlayStation Vita and are due for release in the summer of 2013 under the name Stealth Inc: A Clone in the Dark. Curve have also announced plans to release the game for iPad and iPhone.
