I got this book before I got the game, so I had some time to look it over before I played it. I didn't get the regular strategy guide so I don't know how good that one is.
To start out the book is hardback with a folded up piece of laminated paper. With the paper fully unfolded it has full printer paper sized maps of all the multiplayer maps online. The maps are covered with plastic to act as a dry-erase board. This is helpful to help plan out strategies and to plan out your attack with your team online.
The book is very nice and is well detailed. The guide is very good and covers the game in-depth. It has a walkthrough of the entire campaign without spoiling any of of the events to come ahead, which I like. It also covers each special ops mission in depth and with great walkthroughs. The third major part of the book (and I say 'major' because it takes up half of the book) is the multiplayer section. This section covers every inch and every microscopic detail that could be covered about the online experience. It covers what multiplayer is and what it is all about, it covers options, it covers extras, it covers achievements, it covers the different types of multiplayer, it covers every single gun and weapon with stats and with all unlockables, it covers perks, killstreaks, and ranks, it has tips and advice; and to top it all off it has every single map for every type of multiplayer with detailed layouts and with tips and tricks to help you along the way. The last little bit of the book covers all the extras and achievements and how to get them, online and offline, that you need to complete the game 100%.
The book has so much information that I still haven't been able to read every part of it yet. The book looks very nice with pictures from the game on every page and with a very nice looking layout.
If you are a Modern Warfare enthusiast looking to complete the game 100%, this guide would be the one to choose.
