Battlecruiser (StarCraft II)

The battlecruiser is the most powerful terran air unit.

Attacks
The default weaponry of the battlecruiser is no longer a single powerful attack although its earliest renders did so. Instead it will fire multiple laser bolts, each inflicting 8 damage. This attack can only target one unit, but once a target is dead, the rest of the blasts immediately move to the next target, thus wasting no attack on any target.

Battlecruisers can destroy enemy structures in only a few volleys.

Abilities
Each version of the battlecruiser is treated as a different unit for UI purposes; double clicking on a Yamato-equipped battlecruiser will select all such battlecruisers but will not select battlecruisers with the Missile Barrage upgrade.

Development
The battlecruiser has undergone some changes in development, such as replacing its Plasma Torpedo ability with a Missile Barrage ability. This was changed as the plasma torpedoes did splash damage, thus overlapping with the role of the siege tank.
 * Plasma Torpedoes: An area-of-effect air-to-ground weapon which dealt damage over time and was effective against weak swarming units (like marines and zerglings). It added multiple small barrels to the front of the ship's hammerhead.
