Rainbowcore Hypernova is a free-to-play fighting game developed by Nucko Games for Windows. The game features seven vibrant characters, each representing a different color of the rainbow, and an easy-to-learn control scheme with three buttons and a variety of motion inputs. The battles are fast-paced and dynamic, with each character having a unique arsenal of moves. The visuals are explosive and set against the backdrop of a surreal underground mushroom cave. Rainbowcore Hypernova also boasts a banger soundtrack that blends epic music with absurd mouth noises. The game uses peer-to-peer rollback netcode gameplay for seamless connection with other players. However, the game contains many flashing images and animations, so an epilepsy warning is in place.
