Dr Brain Action Reaction is a puzzle game developed by Knowledge Adventure. It is part of a game series originally developed by Sierra. The game uses Unreal Engine 1.

This is a decompilation of the .u package files containing all the assets for the game, which I have done with other UE1 based games. Since the game didn't come with the UnrealEd executable and I wasn't able to get the 224 patch UnrealEd executable to work, I used WOTgreal to export the files instead (I used the decompilation option for the uc files instead of extracting the raw scripts, probably not the best idea for highlighting how the game works as this tends to omit certain minor details). I also uploaded the assets instead of just the .uc files, which I didn't do with the other games.

I don't really plan on using any of this to make a patch for the game or anything like that, I was just curious about how the game worked.

None of the code or assets have been modified. Though some of the asset files may have been exported incorrectly.
