The Heat Seeker is an unlockable buggy in Jak 3. It can be purchased for fifteen Precursor orbs. It has a very minimal base frame, with a bronze-colored hood, and is single-seated. It has dual machine guns, and a fairly decent turbo, but is still rather hard to control.
Its performance is average among the rest of the buggies, having only a little over-average speed and jump, with average armor and weapons.
