Psyonix has released a free update for Rocket League that promises to change the way the game is played through the use of what they’re calling “mutators,” custom match options players can mix and match at will.

Gravity, ball size, ball weight, match length, and ball shape are just a few of the mutators now available in Rocket League. Full patch details are available via Pysonix’s website.

Rocket League launched in July for $19.99 on PlayStation 4 and PC, and has been downloaded more than five million times, including over one million copies sold on Steam.

Last month, the DeLorean Time Machine from Back to the Future II was offered as a $1.99 add-on. Should you be interested in viewing the trailer for that particular piece of content, feel free to click here.
