Alright.. first off, let me say. WOW. I just finished halo, and damn!

I must say that some of the gameplay/leves where a bit
repetetive - even brainless point and shoot (small amount, but I gota be honest). But DAMN, the last level WAS GREAT! I had a little too much driving thru the ship at the end!

Okay, now my questions... I either just didn't pick up the following, or someone walked in and decided to talk to me while a cut scene was playing -

The flood - I don't understand it? Those things take over human's bodies and turn them into.. those things? What do they have to do with halo?

The Robot things (lol) - What the hell are they doing there? and what's with the blue floating 'eye'? why does he 'help' us in the library, but is against us the rest?

Halo - what is it doing that I want to destroy it so badly?

Covenant - as I understand it, we fell on this planet because we where fighting them and the ship got wrecked etc etc.. why are they on halo?

AHH, so confused.. I hope someone, or some people can clear this up - too many things I don't know, and I finished the game already!

Thnx in advanced!!!
