This article describes the Unit Type (StarCraft) or Attributes (StarCraft II). For information on the device, see here.

A detector is a unit or structure with the ability of Detection: it is able to reveal camoflauge, permanently cloaked, burrowed, or hallucinations enemy units. Having enough Detectors across the map is an important aspect of any player's strategy, as they will provide intelligence on potentially fatal attacks from otherwise unstoppable hidden units.

While every race and faction has a mobile detector unit, they also have a passive stationary defense building that provides detection, such as Photon Cannons, Spore Crawlers, and Missile Turrets. Detector buildings lack the mobility of units, but make up for it by being much more durable and by being equipped with more powerful weapon systems. Regardless of which race a player uses, if the opponent uses cloaked or burrowed units, having a Detector in your army before engaging your opponent is pivotal.

StarCraftEdit

Detectors can be stationary (buildings) or mobile (units). Once a detector uncovers a cloaked unit, any friendly unit can fire on it. This capability is especially critical when faced with a ghost targeting a nuclear missile or an arbiter providing cover for a number of units. Detector units trapped in Lockdown or hit by Optical Flares will lose their ability to detect.

List of Detector unitsEdit

Detectors include:

Protoss

Terran

Zerg

Special AbilitiesEdit

Ensnare, Maelstrom, Plague, Stasis field and Lockdown will reveal cloaked protoss and terran units caught in their areas of effect for the ability's duration. Burrowed zerg units are unaffected by these abilities except Stasis Field while burrowed, but if hit by these abilities while above ground, they will be revealed if they burrow. Irradiate reveals all cloaked units it affects and also affects burrowed zerg units. EMP Shockwave will not affect protoss cloaked units or zerg burrowed units, but terran ghosts and Wraiths will be affected and lose all their energy, causing them to immediately decloak.

Non-Buildable DetectorsEdit

These detectors can not be built/transformed/warped by any worker unit.

Terran

Zerg

StarCraft IIEdit

Units in Starcraft II are tagged with one or more Attributes that determine bonus damage, affect targeting, and/or can influence spells and abilities.
