On ONI: Sword Base, there are two areas near where both communications relay stations are in the level that contain two invisible switches. They both need to be activated at the same time, meaning only two players can activate them. After both players activate the switches by holding X, a new objective appears called "Reach Racer" and spawns both players near the main base's exit, along with two Warthogs. From that point on, it's a race around the map and back to the starting point while crossing several checkpoint flags along the way. Once finished, the map resets, but you can replay this minigame as many times as you like by re-activating the two switches. This mode is a reference to the Ridge Racer series.
