GORN is a VR gladiator game set in a Hyborian (Conan-style) arena, lorded over by a troll-like king and attended by floating heads.
It has cartoonish aesthetics and a lot of violence matched with buckets of blood and gore.
It has the distinction of being the VR game that destroyed my old Acer Mixed Reality Headset and prompted the Christmas purchase of a HTC Vive Cosmos.
