How To Install Jedi Knight Levels and Mods

Authors: Jipe, Tallgeese, and Brian

So, you've just downloaded a level or mod, and you want to load it up right away, but you have no idea what to do? Never fear, Massassi is here! Well, now that we've got the annoying cliches out of the way, let's get down to business: describing in-depth how to install user-made levels, skins, weapons, patches, and whatever else you can think of.

2022 Update: Please give Max Manager a try! This program is available in the /programs/ section. It's a modern mod launcher/manager that works on Windows 10+.

Older instructions follow...

Most files you download from the Levels/Mods section of Massassi will be ZIP files, with a .zip extension. They can be opened easily with WinZip, which is shareware - you can try it out for free, then if you like it, pay $20 to the makers. After installing WinZip, double-click on your *.zip file and it should open. Following are detailed instructions for each of the types of files available here at Massassi.



There are several different ways of running mods for JK/MotS. The most popular used to be Patch Commander. You could previously download it for free from, but the site is now defunct. You may be able to get it from another source, although Massassi doesn't currently have a copy and it may not work on newer versions of Windows. Once you've downloaded andinstalled it, read on:

Another way to run patches is via the command line:

A final way to run JK/MotS mods is with a .bat file. Follow the instructions from the command line method above, but extract all but the .bat file to your folder. Then extract the batch file to your main JK/MotS directory, and double click on it to play. You can make your own .bat files, but it's generally easier just to type a line in at the command prompt, or use Patch Commander, if the author didn't include one in the download.


If the skins are in a .gob/.goo file, then you can follow the instructions above for installing mods. If all you have in the zip file is a bunch of mats and a 3do or two, then read the paragraph above on running patches with the command line. The 3dos should be in blah\3do, the mats should be in blah\3do\mats, and if there is a models.dat, it should be in blah\misc; this is assuming your blah directory is either in C:\Program Files\LucasArts\Jedi Knight\blah or C:\Program Files\LucasArts\MotS\blah. Once again, you will need a new folder for each new set of skins.

The most important thing to remember when dealing with custom levels and mods is JK's checksum system. All players in a game need to be running exactly the same patches and levels, or you won't be able to play with each other. It is crucial that all the people who will be playing have the same version of everything and are running everything correctly. If you need any help installing something, head over to the forums and ask. Happy Gaming!
