Everything in here was made by the guys over at http://facelift.quakedev.com/ and packed into .pk3 by a very kind person from www.quakeone.com. All I did was upload it to FPSBanana.
NOTE: You must have Darkplaces in order to run this! Get it from http://icculus.org/twilight/darkplaces/, install it, put the /id1 folder and the included .pk3 file into the Darkplaces folder to play!
