Raiders of the Broken Planet — Wardog Fury Campaign is a story-based addition for a multiplayer shooter with a third-person view. The in-game story will tell you how Harek will try to win Loaht to his side. General Marmalade will try to take over Aleph's energy. Loaht's rage should help one of the sides win the war, and therefore the heroes will try to be the first to get to this character.
The add-on requires the original version of Raiders of the Broken Planet.
