I completed the game, which I have to say is one of the best video gaming experiences I've ever had, then had to play through it again, this time with the strategy guide so I didn't miss anything. And with this book I didn't. Everything is in here; maps, weapon and enemy guides, a full walkthrough and all beautifully presented. Being the limited edition hardback version it also looks and feels the part. The only other recent(ish) strategy guide that comes close in information and quality is Dark Souls: The Official Guide
. If you are a fan of BioShock Infinite I recommend you buy the guide then play through the game first unaided then again with the book. A must buy in my opinion.
