Install Guide

What You Need

• USB flash drive (FAT32 formatted)
• Unreal Tournament 3 (BLUS30086) for PS3
• A computer to download mod files

Step-by-Step

1. Download the mod file — Download the USERDATA.JAM file from the mod page. You can do this on a PC, phone, or even directly from the PS3's built-in browser.
2. Place USERDATA.JAM at the root of your USB drive:
   USB Drive/
     USERDATA.JAM
   That's it — no subfolders. The file sits directly in the root of the drive.
3. Plug the USB drive into your PS3.
4. Launch Unreal Tournament 3.
5. Go to: Community → My Content → Import Mod
6. Select the mod and import it. Done!

IMPORTANT: The USB drive must be FAT32 formatted. Most USB drives come pre-formatted as FAT32. If yours isn't, you'll need to reformat it (this erases all data on the drive). exFAT will NOT work — PS3 requires FAT32.

Historical note: If you find older guides referencing PS3/SAVEDATA/BLUS30086-MODIMPORT/USERDATA.JAM — that was the pre-Patch 1.1 install path from UT3's December 2007 launch. Patch 1.1 (March 2008) and every patch since, including the Titan Pack, look for the JAM at the USB root. The old path no longer works.

1. Download the PC mod file (usually a .zip or .ut3 file).
2. Extract the contents if it's a .zip file.
3. Place files in your UT3 directory:
   Documents/My Games/Unreal Tournament 3/Published/
4. Launch UT3 — the mod should appear in the appropriate menu.

"No mod found" or mod doesn't appear in Import Mod

This is almost always a folder structure issue. The PS3 is very strict about the exact path. Double-check:

• The folder must be PS3 (not "ps3" or "Ps3" — all uppercase)
• Inside PS3: SAVEDATA (all uppercase, one word)
• Inside SAVEDATA: BLUS30086-MODIMPORT (all uppercase with hyphen)
• The file must be named exactly USERDATA.JAM
• Make sure there are no extra folders — USERDATA.JAM should be directly inside BLUS30086-MODIMPORT

PS3 doesn't recognize the USB drive

The PS3 only reads FAT32-formatted drives. If your USB drive isn't detected:

• Check the format: Right-click the drive on your PC, select Properties, and look at File System. It must say FAT32.
• Reformat if needed: On Windows, right-click → Format → select FAT32. On Mac, use Disk Utility → Erase → MS-DOS (FAT).
• Large drives (64 GB+): Windows may not offer FAT32 for drives over 32 GB. Use a free tool like Rufus or FAT32 Format to format larger drives.
• Try a different port: The PS3 has multiple USB ports — try each one.
• Try a different drive: Some USB 3.0 drives have compatibility issues with the PS3's USB 2.0 ports. Older, simpler USB drives tend to work best.

Mod imports but doesn't work in-game

If a mod imports successfully but doesn't appear in menus or causes issues: (1) Make sure you're looking in the right place — maps appear in the map browser, characters in character select under specific factions, mutators in the mutator menu. (2) Some mods require specific game modes to be selected first. (3) Try restarting UT3 after importing. (4) If the mod crashes the game, the file may be corrupted — try re-downloading it from UT3MOD.COM.

How to delete/remove an imported mod

To remove a mod you've already imported: Launch UT3, go to Community → My Content, find the mod in the list, select it, and choose Delete. This removes the mod from your PS3's hard drive. You can always re-import it later from your USB drive.

• Keep your USB drive handy — Create the PS3/SAVEDATA/BLUS30086-MODIMPORT folder once and reuse it. Just swap out the USERDATA.JAM file for each new mod.
• Organize your downloads — Create a "UT3 Mods" folder on your computer and save downloaded USERDATA.JAM files with descriptive names (e.g., "DM-Deck17-USERDATA.JAM"). This way you can re-import them anytime.
• Try mutators with custom maps — Mutators work with any map, including modded ones. Low gravity + a tall deathmatch map = instant fun.
• Play with bots — Even with official servers offline, UT3's bots provide challenging opponents. Set bot count and difficulty in match settings for a great solo or split-screen experience.
