Yeah, sorry about that, I started the tutorial a little bit in medias res xD. I should have started it with finding aiskills.uexp, but anyway I can try to explain it: To find aiskills and basically anything else inside the game, you need to extract one of the paks from the game. Generally speaking you can find the paks in your game folder, *BUT* in this case I'll extract Biker's Project 20 mod ( www.racedepartment.com/downloads/project-20.32568/ ). Now to extract this pak you need some reverse engineering tool. To that I use QuickBMS (aluigi.altervista.org/quickbms.htm ), because it's quite simple to use and can be used to other games as well! To extract the pak using QuickBMS, do following: When you open the program, it'll pop up three windows in total. Firstly it asks for a BMS file. The file you need to choose, is this one - aluigi.altervista.org/bms/unreal_tournament_4.bms Secondly it asks you an input. This is the .pak file you want to extract. And lastly, it asks you for an output folder. It's just the folder, you want it to extract out. Then it starts extracting and you should after few seconds see the result! Now you can find aiskills.uexp by going into youroutputfolder\motogp20\Content\assets\data\Gameplay\AI\Skills . Open it up using your preferable hex editor.
