The mode, which requires the Nintendo Labo VR goggles, is compatible with limited, timed offline battles and allows players to look around the scenery as CPU players battle it out, or a single player fights against CPU.
“Dozens” of stages support the VR mode, according to Nintendo.
The Nintendo Labo VR Kit itself was also released in April and is the fourth entry in the family-friendly build and play series.
It features six cardboard sets designed to be used with accompanying software. These include the Toy-Con VR Goggles, which sit in front of the Nintendo Switch hardware itself, plus the Blaster, Camera, Bird, Wind Pedal and Elephant Toy-Con projects.
The full Labo VR Kit costs $79.99 (£69.99), while a starter set featuring the Goggles and Blaster is available for $39.99 (£34.99).
