The Ball is a total conversion of Unreal Tournament 3 into a clever physics puzzle game controlling a massive Aztec metal sphere. Released back in 2009 and eventually a full game release, this mod is a free-to-play version if you own Unreal Tournament 3. Push, pull and use physics to guide the ball through intricate puzzles with moving elevators, triggers, water and much more!
I was able to install Unreal Tournament 3 in Heroic Launcher and then install The Ball files into its own prefix.
Look through the prefix and find The Ball folder in "My Documents".
Move the folder to your Linux
Documents folder in "My Games/Unreal Tournament 3"
In Heroic Launcher add the following Game Arguments (In Settings then Advanced):
This will allow it to launch Unreal Tournament 3 and then find The Ball game files instead of UTGame files.
The game ran almost perfectly...
