The first new course is called Shelltop Sanctuary, and consists entirely of Par 3 holes. It will have a "pro" and an "amateur" mode that will greatly affect the positioning of the green. The other new course is All-Star Summit, which uses illustrations of various Mario characters as a motif. It also includes features like brick blocks that can be broken to refill energy, clouds that can be used to travel across the course, and Star Coins that can completely refill your energy gauge.
The new mode "Target Golf" tasks players just with teeing off into a large target, awarding points for whoever can hit closest to the center of the target. "One-On, one-Putt" forces players to complete holes in only two strokes - one to get on the green, one to sink the putt. This mode will only be available on the New Donk City and Shelltop Sanctuary courses.
Update 4.0.0 for Mario Golf: Super Rush is available now.
