Quadrilateral Cowboy is a retro-hacking heist game in which you dial into security systems with your trusty 56K modem to open doors, disable security, and perform other feats of digital derring-do in the service of the highest bidder. It's quite good, “a smart puzzle game, overflowing with personality,” and now developer Blendo Games is giving players the opportunity to hack it up for real by releasing the source code. 

“Quadrilateral Cowboy uses the idTech 4 (Doom 3) engine. The source code is written in C++ and includes the solution files for Microsoft Visual C++ 2010,” the studio said in a note on the FAQ, which includes the download link. “The source code is released under the GPL license.”

He also offered a pretty good idea for what someone with the appropriate expertise might want to do with it:

Chung also recently committed to providing “deleted scenes” from the game as extra levels, which will be available for free via the Steam Workshop.
