DESCRIPTION:
The following video has both the Physis, and Mythos versions of the remastered version of this song "Straight Ahead" from Mega Man Zero 4. I personally love this track for not only being effectively a 'rehash tribute' of Sigma Fortress 1 in Mega Man X, but making something new out of it. I love both versions, so I thought I would share them.

Both songs are by III, and on the Physis, and Mythos Mega Man Zero Remastered Soundtrack Albums respectively.

0:00 Physis version.
3:02 Mythos version.

Zero is owned by Capcom. I do not claim to own the art shown in this video, all the characters depicted in this video are owned by Capcom.
