Does anyone still have the files for these? I want to include the darktrooper in 1 of my levels and replace 1 of the current weapons like say the concussion rifle with the assault cannon.
I do remember a user named savagex or something like that, that had recreated these for use in jedi knight levels. Any help would be most appreciated.

The various darktrooper models (phase 1,2 & 3) are in a mod that was made for MotS, called Halowan 4, a mod that is not on Massassi. (I'm not sure it is still available for download anywhere, but I'm sure I have it somewhere.)

The phase 3 dark trooper though, is also in a JK mod called Return of the Empire. There are two versions of it, I linked you to Version 2.

Hope this is what you need!

If the assault cannon weapon is the big cannon from Dark Forces I (the arc-shaped thing with all the ammo visible), then it's also in this mod.

You should also try to get in touch with the author(s) to obtain permission before using their material in your own projects.

Very true, I should have mentioned that. My apologies.
