Guardians of the Galaxy Remix is an expansion for Marvel United that adds a ragtag group of three new Heroes, a fanatic Villain, new Locations, and a new Challenge mode. The Guardians are a resourceful and tightly-knit group that excels at working together against all odds. Withstanding the relentless onslaught of Ronan, the Accuser, will take everything they have. It may even call for an off-the-cuff Plan B.
