This week, PlayStation Plus members can take to an ever-changing race track when Sonic & All-Stars Racing Transformed enters the PS Vita Instant Game Collection. The ‘transformed’ part references the fact that your go kart isn’t always cemented to the pavement – if your route should all of a sudden require your little kart to, say, fly, it will. Yep, your vehicle is constantly morphing back and forth between kart, plane and boat, so you’ll have to master each type if you want to win.

You can download Sonic & All-Stars Racing Transformed on PS Vita and take advantage of all these PS Plus discounts after the PlayStation Store updates tomorrow, 12/24.
