Toronto-based Rocket League pro Treyven “Lethamyr” Robitaille is showing his love for Fall Guys by recreating the smash-hit battle royale’s maps in the Rocket League Workshop on Steam.

He’s already made great strides in adapting the Slime Climb mini-game:

The pro player, coach, and streamer first teased his passion project on Twitter on August 13, then quickly followed through with a live stream of his custom map-making, drawing useful input from his viewers.

Lethamyr’s tweets in the following days show that he was still at it — and making great progress, to boot.

To recreate the Fall Guys levels on Steam’s Rocket League Workshop, Lethamyr has been using Blender to plot the environments and Unreal Development Kit to import the map. 

Up next on his to-do list is to run a 60-player stress-test for his custom Slime Climb map. His Patreon supporters from Tier 2 and up will get first dibs to join.

Best of all, it looks like Lethamyr is showing no signs of slowing down. He’s got Hex-A-Gone next in his sights:
