Later this year, developer Flying Wild Hog is planning a reboot of shooter Shadow Warrior. In advance of that, you can enjoy the source material for free on Steam.

The original Shadow Warrior was developed by Devolver Digital and published by 3D Realms in 1997 using a similar engine as Duke Nukem 3D.

Currently, Flying Wild Hog and Devolver are working on a reboot – sans offensive material – for the PC (later this year) and next-gen systems (in 2014).
