Metroid Prime 2: Echoes is a very hard game. I got stuck on it pretty early, but I knew I was up for a challenge because I played the first game. So I bought the strategy guide. It helped a LOT.
Just like most strategy guides it leads you step by step through the whole game. It skips unnecessary parts that are obvious like going to a certain room to get to the next part. It explains what you have to do pretty well. It is an attractive book with lots of colors. It spans 238 pages.
The only real complaints I had with the guide are that Nintendo Power could have put more screenshots for the game while going through it step by step. They focused more on huge shots of Samus taking up a whole page (which is really unnecessary). The other complaint is that sometimes they will skip through certaing rooms, which some players might not like.
Overall this is a very good strategy guide. I recommend it for anyone stuck in the game!!
