There are jump pads at the ledges that cause you to jump much higher than normal when you stand on them. There is also an arch that blocks the central part of the top blast zone, making it more difficult to score vertical KOs.
When the items are turned on, occasionally ARMS Drones will carry items to the stadium. The fighters have to attack the drones to drop the items, allowing them to be used.
Spring Stadium is Spring Man's home stage in ARMS. It is an open-air stadium owned and operated by the Spring Gym.
