Former Capcom producer Keiji Inafune had a surprise for PAX Prime attendees at this year's event. The Mega Man creator announced that the Mighty No. 9 beta was ready to launch for anyone that backed the game's Kickstarter. Those that gave money to the campaign should check their e-mail now for a downloadable Steam key.
The beta is meant to coincide with the one-year anniversary of the game's original announcement. At the moment, it's only a single level, with the possibility of additional levels coming later. The beta is only available to Kickstarter backers and to the PAX attendees that attended the game's panel, though there's a possibility that it could hit Steam Early Access in the future.
