Here's a small sampling of the Wily Numbers Instrumental tracks that come with pre-order copies of Mega Man 11. The video above covers Block Man, Fuse Man, and Impact Man themes.
For the uninitiated, these are alternate tracks that play during the game. The only method to obtain them (so far) is via pre-order. So if you've got your copy of Mega Man 11 reserved, these themes will be available to you at launch!
