List of StarCraft II units

The following is a complete unit list for StarCraft II multiplayer game units to date, compiled using recent official sources as well as information from fansites that had access to official information. StarCraft II was announced on May 19, 2007. The unit list has undergone numerous changes since then.

All three races will be available in the multiplayer skirmish mode in each of the three StarCraft II products.

Units

 * Purifier: Formerly known as the soul hunter, the purifier was an infantry unit. Its attack was effective against biological units and buildings but was weak against mechanical units and robots; purifiers could gain power from draining biological units as well, firing one beam (originally) going up to three beams when fully powered up.


 * Reaver: The reaver was originally supposed to make it into StarCraft II, but was cancelled before BlizzCon 2007. Its current fate is unresolved although Blizzard Entertainment is working on a replacement.


 * Tempest: Originally set to replace the carrier, the original was brought back, due to "emotional connections with the original unit".


 * Star relic: Aerial spellcasting unit.


 * Stasis orb: Some of the abilities of this unit were moved to the nullifier.


 * Twilight archon: A large ground unit, swirling with blue energy and shooting short-ranged blasts of energy, very similar to the archon.

Structures

 * Obelisk: Protoss support structure, formerly known as the dark pylon, with special macromanagement abilities. It was canceled as of February 2010.
 * Observatory: Unlocked observers. Observers no longer require anything more than a robotics facility to be built.
 * Phase cannon: A defensive building very similar to a photon cannon. It could move within the range of the warp matrix it was on. It is no longer in the game.
 * War beacon: Previously used to unlock the colossus.
 * War shrine: This structure used to research the zealot's Charge ability.

Raven-Created Units
The Raven creates devices that have a use in combat.
 * Auto-turret: A defensive combat structure.
 * Defensive drone: A device which intercepts incoming shots.

Add-Ons
In StarCraft II, terran add-ons work quite differently. Only two add-ons have been described, the nuclear reactor and the tech lab. Instead of being specific to an associated structure, each add-on can be added to any barracks, factory or starport, granting a specific benefit. One structure may only have one add-on attached to it, so it cannot benefit from the reactor's bonus and the tech lab's bonus simultaneously.

Units

 * Cobra: A fast hover vehicle equipped with an electrical attack that slows enemies. It has since been canceled.


 * Firebat: Firebats were much larger and tougher than they were in the original game. They were built from the factory. They have been removed from the current build to test the Marauder, though they may return if the marauder does not make it into future builds.


 * Predator: An air to air unit; it was canceled during development.


 * Medic: Healing ability of this unit moved to medivac dropship.


 * Mine drone: Built by the raven. Has been replaced by spider mines.


 * Spider mine. Seemingly removed as of April 2009.


 * Targeting drone: Placed a target laser on a given unit. Units took 50% more damage while being targeted. Canceled as of April 2009.

Structures

 * Munitions depot
 * Radar tower
 * Shadow ops: Replaced by the merc compound as of April 2009.
 * Star base: This permanently flying structure was an upgrade of the starport. It produced units despite flying and could "re-arm" nearby units (increasing their energy pool). It was featured at BlizzCon 2007 but has since been removed due to balancing issues observed at that event.

Units

 * Infested protoss: Produced from infested protoss buildings. This unit was removed from the latest build.
 * Large Queen
 * Huge Queen
 * Morphalisk Removed as of February 2009.
 * Swarm guardian Similar to the original guardian, evolved from the mutalisk, but spawned broodlings when it struck. Replaced by the brood lord.
 * Swarm They used to be created by swarm guardian attacks and destroyed structures. They have been replaced by broodlings.

Structures

 * Infested protoss buildings: The ability to infest protoss structures has been removed from the latest build of StarCraft II.
 * Infested terran buildings: The infestor had the ability to corrupt terran structures temporarily. These structures released s. Infested terrans are spawned directly from the infestor now.
 * Shrieker: This structure enhanced the range of the swarm clutch. It has since been canceled.
 * Spore colony: This structure defended against air attackers and could uproot from the ground, gaining mobility but reduced hit points. It was removed and replaced by the spore crawler.
 * Sunken colony: This structure defended against ground units and could uproot from the ground, gaining mobility but reduced hit points. It was replaced by the spine crawler.
 * Swarm clutch: When these eggs hatched, they disgorged attackers to defend the base. It has since been canceled.
 * The queen had the ability Swarm Infestation, which modified other zerg structures to defend themselves temporarily.
