First chapter reads like a gamefaqs walkthrough. The sentence about watching the ammo read-out on the hud and when to switch clips, or the exact copy of the dialogue from the game. Hey, I like Halo, but the dialogue in game kinda blows for a book. Plus there's a big inconsistancy between Fall of Reach and Halo(game)/Halo: The Flood.
Ill probably power through this to get back to the good Halo books, but YIKES. If Nylund isn't doing the writing its pretty blech. Im pretty pumped to read First Strike and Ghosts of Onyx tho.
