Halo 5: Guardians is probably the biggest Xbox One game of the year. Microsoft's Halo series has been beloved ever since the first game debuted on the original Xbox console way back in 2001. Along with each new game in the mainline series comes a variety of ancillary products for fans to consume, including books, comics, toys, controllers, and even movies and TV series. This one is no different ? we've already reviewed the Halo 5 Limited Edition controllers, in fact. Another supplement each big Halo game receives is a strategy guide from Prima Games. This time, two guides are available: a standard softcover edition and a hardcover Collector's Edition. Both versions include a free digital guide, but the hardcover guide packs some enticing bonuses as well. Read on for our full review of both guides and a look at the Collector's Edition physical and in-game bonuses!
