Today, Psyonix announced that starting next month Steam Workshop Levels are coming to Rocket League. Once live, players on PC, Mac, and SteamOS will be able to upload custom levels they have built to the Steam Rocket League Community hub.
Psyonix had the following to say about the announcement:
The Rocket League modding community like our fans on the RocketLeagueMods subreddit, have built some fantastic stuff using the Unreal Engine 3 UDK over the past year — including frenchfries’ own Rocket League Obstacle Course (pictured above) and Dribbling Challenge #1 to name just a few. With our new Steam Workshop support, it will be much easier for modders to share creations without having to edit game files.
Psyonix has said it will have more info on the update — which will arrive sometime in December — in the coming weeks. Meanwhile, you can check out more information about how you will be able to upload and play Steam Workshop created content, here.
