Does any one remember this Quake total make over mod? http://www.zerogravity.com.au/portfolio0601.php
Got bored today and did a little poking around, Turns out (assuming you have the Quake Quest installed and working) if you take the files (that can be downloaded from the page above) extract the xmen folder and copy it into your quakequest folder then add -game xmen to the config.txt file you are basically good to go.
Only got to play the first level so far, I'm not good at it at all, but weapon location is odd, and it would awesome if some one could get the fist to work like Dr. Beef got the ax to work, but biggest question, is there someone smarter than me who can get this into a separate launcher so the config file doesn't need to be edited switch between this and quake?
