      • Showcase Remix - Forest Sprite
        • What happens when you cram a turbocharged inline-4 motorbike engine into a tiny car, and tune it to go really fast off-road? Find out in this returning Showcase Remix, featuring the 1958 Austin-Healey Sprite Mk1 versus the Horizon Motocross Team in autumn.
        • Showcase Remix - Assault On The Control Room
          • Our remix of the Halo Experience Showcase returns! Don’t miss this opportunity to re-run the UNSC Fleetcom training exercise in winter, as it counts towards your Star Card progress as a Racing Superstar!
