you guys should read the halo books, there are three of them.
the first one covers how master chief was discovered as a child along with other potential spartans and where then trained severly. they go on some cool missions, shoot stuff, blow up other stuff, and people die etc.... its a really good book.
the second book is pretty much the halo one game but with more detail and it was written by a different author than the first book. this 2nd book sucked, in my opinion.
the third book was written by the 1st original author and it was really good again. this one covers what happens between the game halo 1 and halo 2 and is a excellent story.
so read the books, they is some good stuff, but only if you acutally know how to read..

or if you like to read...
PS: in the first book they describe what master chief actually looks like underneath his helmet and armor....
