Welcome to Mahalo. Mahalo actually has the best Halo Reach walkthrough available, with a text description of all levels, controls, and even video playthroughs. You can find it here: Halo Reach walkthrough In that walkthrough, you can read that you, at the start of the game, take control of a little boy called John-117.
What you don't know, is that John-117 is going to be Master Chief himself, during the game. So, you don't have to look for him, just play the game, and you will gradually see John-117 develop into the great Master Chief himself. Enjoy!
The other guy who answered is lying or just never played Reach. SPOILER : At the part where the thing gets blown up there is a cutscene where you can see Master Chief still in the cyro chamber or whatever its called. Alot of people were hoping for the ending to be Chief getting out of the chamber.
But if you wait after the credits there is the bonus mission. Here is the vid. youtube.com/watch?v=NRrv6rcu90Y.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
