If you miss descriptor file go to GameFolder/HotDodgeball/Binaries/Win64 and launch what you find here. It should help.
!IMPORTANT!
There is a bug in game that we didn't have time to fix.
If you want to play splitscreen and then multiplayer, you have to restart the game. Otherwise you will be unable to start MP game.
If you find another bugs, contact me!
Have fun!
