Sonic, Before The Sequel - Unstoppable

[@philiplonidier]

Yep. It's used in the final bonus fight (if you manage to get it.) It being a remix of Sonic 2's ending theme is completely appropriate considering the context of its use. It was a pretty amazing game!

It sounds like Scott Pilgrim and Sonic The Hedgehog Fused together. so its Sonic The Hedgehog Vs The World.

[@sslaxx]

Well, it a remix of Sonic 2's ending theme...

[@garfeltrealtbh]

Technically, it also has the main theme of the game in it.

Duh and duh lol it's a mix of the two. It's pretty obvious.
