Metal Gear Solid 3: Snake Eater. The original Strategy Guide had everything you would ever want or need. This seems to be a continuation guide. It gives you the secrets that weren't previously in the official guide... but the secrets that are in the official guide aren't included here. The walkthrough is pretty much the same, just a bit more compressed. The maps, and info presented in the main walkthrough is virtually the same.
There are several things that I wish would've been included in this guide. Truly, this guide should've been an expansion of the original one. For one, they took out the Kerotan locations (though they actually do mention the reward for finding them all). The original guide was 224 pages, and this one is 160. In this case, the numbers don't lie. You won't get nearly as much information from this guide as you would the original. No indepth look on camos or face paint. This includes the new camos you can find in this game.
They have maps for online mode and all, but I find that this is the only plus the guide has really got. New secrets get a mention, but not much of an explanation.
Worst of all? No walkthrough for the original Metal Gear or for Metal Gear 2: Solid Snake. This is unforgiveable. Without a walkthrough for these two games, the guide only further becomes useless. If you want a walkthrough for Snake Eater, you might as well get the original guide. All the extra content isn't explore enough in this guide. Maps for online mode don't make a fantastic guide. A basic walkthrough also doesn't make a fantastic guide. We're interested in the new content as well as the old. And while it does a fairly good job in the original walkthrough (it's basically the same, word for word), it's compressed to fit in the pages. Also, there's no help about CQC. If you're someone who never played Snake Eater and so you invested in Subsistence, this guide isn't going to help you adjust to CQC.
So in short, you might as well get the original guide. It doesn't have the coverage of Online mode or most of the new extras, but you're really not getting that by investing in this guide either.
