Aliens vs. Predator is unlike any 3D shooter that has come before; a brooding, bloody, and dark combat arena where paranoia rules the day and an itchy trigger finger can find you mowing down more friends than enemies.

Aliens vs. Predator is a unique first-person shooter that allows you to choose from one of three classes: Marine, Alien, or Predator. Each of these classes plays differently, feels differently, and each sports its own complement of weaponry. Encompassing both single-player missions and multiplayer mayhem, there is something for everyone in Aliens vs. Predator, and this guide will show you how to get the most out of every experience. Here you'll find strategies for becoming number one in multiplayer battles and to work as a team, whichever character you're playing.

Each of the three campaigns that comprise the single-player experience is documented in a detailed walk-through that is guaranteed to get you through every Director's Cut mission to the end of the game. Additionally, you'll read advanced tactics for each of the selectable classes as well as in-depth advice on the best use of each of the varied and powerful weapons at your disposal. Before you know it, you'll be climbing walls with the Alien like a professional, sitting in dark corners and sniping unsuspecting Marines as the Predator, or holding down the fort with your smartgun as an outnumbered Marine.
