Are you making a scenario, and frustrated by the limitations of the Marathon Engine? Wish you could, say, enable your new weapon (which you've replaced the AR-75 with) on vacuum levels? Want to change the color shift under media? Fux! is your tool! It allows you around some of the hard-coded stuff in the Infinity application itself. (Also works with M2.) Warning-you can really screw up and crash beautifully with this program... be careful! In Bo's words, "If you don't get everything exactly right, you're fuxed."
