The shame takes place in some year in the future where Earth blew up so many times people live on other planets now. The player plays as Master Chief, a cyborg legend guy who can shoot aliens better than anyone else can. It just happens this shame is about shooting aliens, so he's happy.
It starts when aliens are attacking Master Chief. He blows lead into them, and blows up the ship (Wait... it was his ship. Oops). He then lands on a weird thing called a Halo. He gets so reckless, he blows it up. His nanny sends him to his room, so he ignores her, and leaves.
