Capcom has announced a new Mega Man game which will be available on multiple consoles including the 3DS. Besides announcing their E3 plans on the 8th of June, Capcom announced a huge new game which combines a ton of Mega Man games and gives you the same old 8-bit style with a remastered HD look. The collection includes games Mega Man 1 through six, its titled "Mega Man Legacy Collection". I suppose this isn't entirely a new game but it is a collection of old Mega Man games remastered in HD. The biggest disappointment concerning this new collection of games is that it will not be on WiiU, so far it will be available on Xbox one, PC and PS4 this Summer 2015. But the 3DS digital version will not be available until this Winter. I do hope Capcom makes an actual new Mega Man game soon, and releases it for 3DS and WiiU as well.
