Greyscale mod v1 (2012) file

The basic idea behind the mod was to play the game with a greyscale aestethic.
It was a simple experiment to recreate some effect similar to the movie "Sin city", an effect that I liked on said movie, where everything is greyscale, except for certain colours that enhanced certain feelings of some scenes.

i've modified all sprites and textures manually and allowed few sprites to keep the colour.
Few years later i've discovered that you could achieve the greyscale effect more easier by creating your own doom pallete, but it's was late for that time.

Dynamic lights aren't modified, so that will add few colours in the game.
Use the zdoom engine for extra oldschool aestethics (not necessary though).
