Thanks for the STOP! (grin) but I had decided to test it myself before I bought atomic and yup it works with the plain ol' duke 3d edition. Though I have to admit, the default controls do need to be changed, there is no way to strafe and the mouse look / forward thing is way hard to control. time to start playing with the config. I have to say though it is VERY fast. and a lot of fun (till I get killed because every time I try to aim I run past who I am aiming at)
