Help! Have not played proper Halo campay for years! I am yearning to play proper halo, such as Combat Evolved, 2, 3 or ODST, as I prefer to go solo, rather than be in the noble team. What does everyone else's thoughts on this matter?

Not sure what you mean exactly... but while I didn't have the internet last month I played the entire halo story chronologically on legendary. From halo wars to halo reach, to combat evolved, halo 2, halo ODST, and halo 3
