PC and Xbox One owners have a chance to play Rocket League for free this weekend. Between Thursday, July 5 and Monday, July 9, you can download the game on Steam or Xbox One without paying a cent. The free version includes all game modes, playlists, features, and arenas. The one caveat is that Xbox One owners will need an Xbox Live Gold subscription to play.

To encourage players to buy the game, Rocket League and select DLC will be available for 50% off on Steam and Xbox One starting this weekend and running through July 9. That brings the core game down to $10.
