The Halo Essential Visual Guide is a very informative and well written place to go to find information on most in game content. The guide was written によって Jeremy Patenaude and published によって DK publishing. And of course we have acknowledge 343 industries. The guide covers mostly all the content in the games like the characters, weapons, vehicles, foes, and もっと見る in a very blunt, but informative way. For example, if あなた are 読書 about the DMR, it will tell あなた what caliber the gun uses, what branch of the UNSC the gun is used in, the capacity of the clip, what rates of 火災, 火 the weapon has, and much more. The guide also has very clear and gorgious pictures of the content あなた are 読書 about. There are over 200 entries in the guide so your not going to knock the guide out in 20 mins, and that also means that there is a lot of content that it covers. Unfortunately the guide does not cover a lot of canon based material outside of the games. Like the 本 and such for an example. I would totally recommend this guide to you. I give it a 10 out of 5. :) POWER TO THE HALOVERSE!!!
