Guarding the outskirts of the anti-air gun early in Halo 3’s campaign is a quadrupedal Covenant tank called a Scarab. Stepping its spidery legs around a circular complex lined with missile pods, a large crane, and enough foot space to let half a dozen vehicles unload their artillery, the scarab is the largest working unit in the series. A far cry from Master Chief’s scripted encounter with it in Halo 2, this AI controlled enemy has a giant laser cannon and its own hit points, and is transporting a squad of Covenant sentries laying heavy fire. As you stare at it in awe, a question forms: how am I supposed to take that thing down? A couple ways. Focus all your fire on the hull and blow it away, or shoot its legs until they lower, fight your way to the power core, and set off a chain reaction. Both answers are possible in the arena littered with tools of mass destruction.
