Rocket League coming to Mac and SteamOS; free copy will come with Steam Hardware pre-order Those that haven't jumped in the driver's seat for Rocket League will soon have two more platforms to play it on. On top of that, the SteamOS version will also be on the house for anyone that pre-orders Steam Hardware.

Rocket League continues to cement itself as one of 2015's biggest breakout games. In addition to getting a slew of players on PlayStation 4 through its monthly PlayStation Plus frebie lineup, Valve has announced that the game has sold more than one million copies on Steam since its release in early July.

To celebrate this announcement, Valve has announced that Psyonix's driving/sports hybrid will expand further, with a Mac and SteamOS version of the game now in the works. In fact, Psyonix and Valve are sweetening the latter pot by announcing that the game will come free for anyone that has pre-ordered any Steam Hardware. This includes Steam Machines, Steam Link, or the Steam Controller. For those that already own Rocket League, they will receive an extra copy of the game to gift to a friend.

PlayStation 4 and Steam users can already play Rocket League with one another and with SteamOS and Mac also coming under the same Steam umbrella, it's expected that those two versions can also play nice with each other. More information is expected about the SteamOS and Mac versions of Rocket League in the near future. Rocket League is a huge favorite at Shacknews and you can check out one of our recent videos below.
