The Doomsday Device | Sonic

Looks like Robotnik paid a visit to Shadow Moses Island...he's been a busy boy to say the least, having done a lot of modification's to this new toy. He's redesigned the Rail Gun which now serves as a highly destructive Laser Cannon, while modifying the original Laser Cannon on the underside of the mech to fire high explosive, armour piercing shells.

Sonic looks so out of place in this scene, hah.

(If you right click and view image or download, should look slightly more higher res.)
