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.[1][2][3] 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 Linux in April 2013 along with The Teleporter Chambers DLC released the previous month.[4][5] 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 Linux and its soundtrack.[6] 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.[7] Curve have also announced plans to release the game for iPad and iPhone
