Halo 3: The Official Strategy Guide
From Halopedia, the Halo wiki
The Halo 3 Strategy Guide is the official strategy guide for the video game Halo 3 published by Prima Games. It was set for release on September 14, 2007, but later pushed back to September 25, the date the game was released. It contains a detailed map of each mission and multiplayer map, which includes locations of the default weapons. The guide also includes a list of all the Achievements and how to unlock each one, a complete bestiary with notes on typical enemy armament, and an equipment list. The extras section has a list of nine of the 13 skulls (only the gold ones) with notes on what they do as well as recommendations on what skulls to use on what levels. It also covers how the meta-game scoring works, with a breakdown of what enemy falls in what category. The primary layout features a quick walk through recommended for easy and normal difficulty levels on the left side of a page, even numbered pages, and an in depth guide for legendary.
