Thanks to Eric Ruth and his PixelForce NES “de-make” of Left 4 Dead, we now have an idea of what the zombie apocalypse simulator would have been like had it released in the ’80s. Valve is apparently aware of the project and finds the concept “hilarious.” Ruth reveals that he plans to release the full game as a free download in early January 2010 for PC. It features all the campaigns from the original game, including 8-bit incarnations of the special infected, for two players to play through — it is a NES game after all, fancy four-player didn’t exist.

via 8-bit Left 4 Dead leaves modernity behind.
