Not much to say
Firstly, I think the name was a bit misleading. It sounded more like a COD remake than a guide (maybe Call of Duty 4 Interactive Guide or something like that would be a better name).
Secondly, this has nearly no content. I don't really see any reason to put a couple of pages of text and pictures into a flash when you could make a normal document from it and share it on an internet forum instead.
