Battlecruiser (StarCraft II)

The battlecruiser is the toughest terran air unit.

Overview
The battlecruiser fires multiple relatively low damage shots, with the anti-ground attack being more powerful than the anti-air attack. This makes the unit better able to handle groups of weaker, low armor, units. In turn, the battlecruiser's high armor makes it less susceptible to weak attacks. This makes them good against s, s, s, and sentries. However, they are weaker against vikings, corruptors, and void rays.

The Yamato Cannon out ranges defensive structures and may be used to clear out defenses. It may also be used to soften up tougher units or thin enemy ranks quickly. This is especially useful in numbers against void rays, potentially eliminating several before they can charge up.

Wings of Liberty
Battlecruisers are unlocked by playing the "Maw of the Void" mission, available after Valerian Mengsk gave them to Raynor's Raiders in order to accomplish the mission.
