Cars: Mater-National Deluxe is a work-in-progress mod created by me: Yoshiman716, for the PC version of Cars: Mater-National Championship, loosely based off of Cars: Hi-Octane Edition , which is also a mod for PC Mater-National. Previously cancelled due to three reasons: stress in my personal life, lack of time and it being a stand in for my (at the time) dead Hi-Octane game which I fixed during the mod's development, it is now back and hopefully will be completed this time.

About this mod

The goal of the mod is to provide an enhanced experience for Cars: Mater-National Championship, an adding some missing features from the first Cars video game like characters (Sally, the Delinquent Road Hazards gang, etc.) music that didn't make it in, new character models and improved textures, content from the PlayStation 3 and Nintendo Wii versions of Mater-National, etc..


One or two versions of the mod are available for download here. Take your pick... or just try both.

Alpha 3 (Patch)

Alpha 3 (Patch) was released on 08/03/2017 and it really wasn't that different from the original Alpha 3, with being just a patch and all. It fixed a few minor bugs, and made some minor adjustments to improve the general experience.

Download: (reuploaded because it got copyrekt) 

Installation Instructions: Replace the DataPC folder in C:\Program Files (x86)\Steam\steamapps\common\Cars Mater-National (or if you are using a physical copy, then C:\Program Files (x86)\Cars Mater-National) with the one found in the .zip archive. Make sure you back up the one you are replacing in case you don't like the mod.

Beta 1

Beta 1 is expected to be released anytime from early August to mid-September.

Addable Mods

These contain content that doesn't come with the main mod's download. Said content is either cut content that was originally supposed to be in the main mod, but didn't make it in in the end but I didn't want to get rid of all my hard work and also wanted people to see it so I just released them as a separate download, or content that would be a little too much (or even too little) to ask for in the main mod. Addable mods are released either alongside a new version of the main mod, or sometime after a version's release. And as a sidenote, all of these addable mod's data will still be left in the main mod's files, just disabled. So if you can't be bothered to download these and/or you have the skill to do it, you can enable them yourself if you wish.

All non-playable characters playable (for Beta 1)

This would have been part of the main mod, but I feel like if I did that, it'd just become a second Hi-Octane. Most of the playable data for the characters was already finished, however, and I didn't want to get rid of it all and I also wanted people to see it, so I made it an addable mod for those who want it.

Mater's Speedy Circuit and Monster Truck Mayhem (for Beta 1)

These are the only two tracks I plan to add to MN DX... ever. If I add any more, then, once again, I'm worried the mod will become too similar to Hi-Octane. Even adding these two as addable mods is pushing it a bit, but I felt I needed at least some new tracks in any way, shape, or form. This had to do.
