The game had a demo that was going to be released first when Nintendo e-shop for the 3DS was up. The demo was to be named as the prototype. The demo would contain levels that would not be included in the actual game, and you would play as Barrett.
The game Mega Man Legends 3 was canceled along with it's prototype not even being released which was to be sold for $5. The prototype would be used to gauge how badly people wanted a sequel to Mega Man Legends 2. The games were canceled for an unknown reason. And online petitions have been started to try and get it made again. The game is a complete disappointment. Was being made by Capcom like every other Mega Man game.
