3D Realms' Shadow Warrior, originally released in 1997, is back as a free-to-play game available for download for both OS X and Windows through Steam, according to Samit Sarkar of Polygon.
Based on 3D Realms' Build engine, used to create Duke Nukem 3D, Shadow Warrior is a first person shooter in which the game's protagonist, Lo Wang, faces off against vile creatures controlled by the evil Master Zilla, a crazed megalomaniac.
A pastiche of tropes from bad martial arts movies of the 1970s and 80s, Shadow Warrior lampoons the genre much in the same way that Duke Nukem 3D made fun of 1980s Hollywood action hero movies. Shadow Warrior received some heavy criticism at the time for perceived racially insensitive Asian stereotypes. Still, the game is fondly remembered by many first person shooter enthusiasts for pushing the once-popular Build engine in new directions.
Shadow Warrior has been resurrected as free-to-play through Steam as a promotion for a new game based on the property that's currently in development at Flying Wild Hog and Devolver Digital, planned for PC and console.
Mac players should bear in mind that this isn't the MacSoft port of the game - this is the original DOS version, running in DOSbox emulation.
