E.G.G.M.A.N.

Inside the two stories—Hero and Dark—we made the musicality differences that symbolize each character in Sonic Adventure 2, where the stages of each character were scattered over, as the focus. Among those, we made the keyword of the composition related to Eggman as “minimal development with industrial system,” but it’s Rough Cutt’s Paul Shortino who was known for his elegant singing voice performing his theme song. Eggman will no doubt work out his master plan even today while humming this song.
