Mahalo happens to have a Halo Reach walkthrough. At mahalo.com/halo-reach-walkthrough they even provide some videos to help you in your quest. It also list the achievements.
Mahalo has many walkthroughs for other games too if you ever get stuck.
The best place to look for a halo walkthrough, I have a few suggestions 1st is probably the halo website, they tend to produce a book/magazines on walkthroughs to the game, 2nd you can always ask on gaming websites, I use gamesforum. Com, im sure if you posted the question on there someone would definitely give you some answers, 3rd would be to look in all the current gaming magazines, I know both xbox and ps have their own magazines in, and seeing that its a new game im guessing that they will have a large spread at least about it, hope these help ;).
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.
