I had bought my 10-year old nephew the game as a gift for his PSP. He hit a point where he just couldn't move to the next level - and this book solved the dilemma. It's filled with the details he needed. He absolutely loves the maps, tips, descriptions and pictures of everything - and, most importantly, it's kept playing the game enjoyable for him.

While some other reviewers point out that it's possible to find more detailed instructions on-linem for children & on-the-go players, I think this book is the solution. Just grab the book with the game and PSP, and it's complete, enjoyable entertainment when out and about.

This guide helped us find every thing we needed to complete the game at 100%. Lego Batman has been the best game in the series to date.

I recommend NOT wasting the money on this guide. It seems only half-finished with very vague descriptions of the different character and item uses. The guide may help you get through minor areas of the game, but it does nothing that a few moments of game-play problem solving wouldn't help. The maps are helpful, but as far as percentage-completion is concerned you're better off finding a walkthrough online- it would be far more accurate and thorough. While I'm certainly not looking for "cheat codes" I would appreciate it if the information in this guide was at the very least detailed and correct. For example, it would be better if it read "In order to unlock this character, you must complete X,Y,Z" or give accurate descriptions of each character's abilities (in at least three cases, we found that these were incorrect or too vague to be useful - i.e. Catwoman has the ability of security clearance, but at which points specifically?). This guide is absolutely not worth the money to purchase it. If a particular point confounds you it would be a better use of your time to simply google the level on which you are stuck.
