DUCKKY25, As far as I know ATS is supported only steam.

Cool Pic! +1 Be sure to check out my gallery!

Btw, is it only available on steam atm? I dun really like steam and im planning on getting the digital download instead. I went to the ATS website but it doesn't show that i can buy the game without using steam. By any chance, do you know if it's gonna be available for download on the website maybe like a day after?
