Shadow Warrior from Devolver Digital and Flying Wild Hog, the last known for the science fiction FPS Hard Reset, is an all new re-imagining of the classic 3D Realms game. Its goal is to combine the original humorous atmosphere and retro fun with modern technology and options, while removing potentially racist elements as well as the multiplayer functions. While nothing is certain, trailers like the following show it's certainly on the right path.
Shadow Warrior will be released for the PC on the 26th of September. Next generation console versions have also been announced for release in 2014.
