Guardians of the Galaxy
This is a band of space mercenaries, your classic motley crew, who are notorious for protecting the galaxy (at reasonable rates). Lead by Peter 'Star-Lord' Quill and based out of his inter-galactic spacecar the 'Milano'. Never fear, when the Guardians are near... or at least that's what they want you to believe.
Note: This group is listed simply as Guardians on the game itself.
