Created by Keiji Inafune and an all-star team of veteran devs, Mighty No. 9 is a challenging side-scrolling action game that transforms the feel of 8 and 16-bit classics, as players remember them, into a fresh modern-day classic.
In the year 20XX, breakthroughs in robotic technology have ushered in a new era of peace & prosperity. Violence is confined to the Battle Coliseum, where robot combatants face off in spectacular duels. Dr. White created 9 robot siblings known as the "Mighty Numbers", who were the most popular and powerful team of robots in the Battle Coliseum and always in the top ranks.
