Hey!
Don´t get me wrong. I love playing Shooters using mouse and keyboard for online gaming. But storytelling campaigns are great on TV with a bottle of beer on my couch, too 
Meanwhile, the most Source Games work with an xBox Controller but i´m can not work out, how to play black mesa with it.
Solutions anybody or lust to text some more code to make it work properly?
Greets from Germany and a profound bow to the game designers!
