Half-Life : Prima's Official Strategy Guide

With a wealth of information, statistics, and gameplay guidelines, this book can help turn any fledgling scientist into a battle-hardened killing machine in no time. In addition to descriptions of the weapons you'll find and the enemies you'll have to use them against, the book offers advice on basic first-person shooter tactics (how to circle-strafe, for example). A full-fledged walk-through of the game includes plenty of maps (more than 100 in all) and screen shots to help illustrate the best path to take. A brief section on multiplayer Half-Life rounds out this impressive guide.
