Pity the lowly Mongoose. It's outshadowed by the flying vehicles in Halo 4. And it's not even the coolest ground transportation in the game, either. This humble ATV is what you use when nothing better is available.
But Achievement Hunters found a way to make the Mongoose one of the more exciting travel options in 343 Industries' first Halo game. Hopefully, this grenade-jumping will become a competitive folk game inside Halo 4.
