The tool should be able to start game once launched. If it fails to start the game you should probably change the content of variable "GamePath" according to you're installation location.

Please download and install Autohotkey before using the script. You can download it from here:

This autohotkey script will add a semi autorun function to the game. I've written this script a long time ago and use it on many games I play.
Thought to share it because it's a handy thing to have. Autorun is Semi, because on pressing the mouse thumb buttons it will simulate key press W down or up.

It does not really matter if you start the script while the game is running or not. If you start the script first and you use the steam version, the sctipt will probably fire up the game for you. If you start the script while the game is allready running it will just capture the proccess.
