A major leak for Forza Horizon 4 has revealed the racer will likely feature a level inspired by Halo: Combat Evolved's Silent Cartographer Mission.

The leak, which came in the form of a huge image-dump on Imgur (via Eurogamer), included an image of Halo’s iconic Warthog all-terrain vehicle sliding around a beach, while a segment of Halo’s vast ringworld arcs into the sky in the background.
