Stealth Bastard

Steal Bastard or Stealth Bastard: Tactical Espionage Arsehole is a Freeware stealth-based game by Curve Studios. Unlike most stealth games, this game is a Platformer.

The objective of this game is to avoid cameras, robots, laser beams, circular saws, and other deadly obstacles in order open up and reach each Level Goal.
