Stealth Bastard is being polished up for a full commercial release through Steam.
The new version, Stealth Bastard Deluxe, apparently comes with a number of new features. Director Jonathan Biddle shared a screenshot on Twitter, showing off new equipment options. The developer also noted that levels will download in the background, and said the new version will launch on Steam in November.
Stealth Bastard hails from Curve Studios, the team behind Fluidity and Explodemon. Its freeware release was extremely well received, totting up 35,000 players in a single week.
