Here are my thoughts. You can ignore them if you want.
1 - The Intro is far to long. I want to read your guides, not site through a 10 second fade in of the DayZ logo. When I first opened the site, I thought perhaps it hadn't loaded or something and was about to close the tab.
2 - I don't want a Prezi like presentation that I have to navigate through. What if I have to find a specific piece of information?
I get that you're trying to make a trailer style intro to the DayZ game. Why not make a Video with the important parts of the text, have that play on the user's request, and then go into the actual guide?
These are just my opinion, and i'm not trying to discourage you. You have a great idea, now you just have to implement it properly.
