I will never forgive Valve for what they did to Half Life and leaving the fans with an unresolved story do not play any Valve games until they make Half Life EP 3! send a message and vote with ur wallets

is there any way to play this with a mouse and keyboard ?? any third party software ?

It seems I can't play with a keyboard, and the only controllers I do have with USB support (Pokken & Gamecube for Switch) are incompatible. What kind of controller can I buy that'll work with this game?

I just got my Steam Deck today and wanted to play this to test it out. After the initial cutscene where it seems like the game is about to start, nothing happens and no buttons work. It was still on the default controller layout. I opened the Steam menu and tried to manually select one of the official layouts, but instead the selected layout is just showing as "#Title" no matter which one I try to select, and the button commands are always empty. I can't get back to any actual layout since this happens no...
