StarCraft/Protoss units


 * Cost will be referred to as X/Y. X is the amount of minerals needed, while Y is the amount of gas.

Wikipedia has more on this subject.
 * There are 3 damage types other than normal: explosive, concussive, and splash.
 * Explosive does 100% to large units, 75% to medium, and 50% to small.
 * Concussive does 100% to small units, 50% to medium, and 25% to large.
 * Splash deals damage to all units in a certain radius (1/2 damage to units 1/4 pix away, 1/4 to those 1/2 away). Linear splash means that the attack travels in a line.


 * Protoss HP will be referred to as X/Y. X is their hit points, which do not regenerate, and Y refers to their shields, which do regenerate.


 * Some unit's damage will be referred to as X/Y, in which case it means the unit uses different weapons against air and ground. X will be the damage done to ground, and Y is the damage done to air.

They are as follows:
 * Some units' attacks are seperated into two parts. That means that each hit from an attack gets some reduction from armor. Likewise, all air attacks get boosts from devourer acid spores.
 * Terran
 * Firebat
 * Goliath air
 * Wraith air
 * VALKYRIE


 * Protoss
 * Zealot
 * Scout air+ground


 * Zerg
 * None!

=Protoss= Protoss units are unique from the other species in that they have shields that regenerate as well as health, which does not. Shields take full damage.

Units are listed on the order that they become available.

Probe
A small robotic worker that mines minerals and harvests gas for protoss created at Nexus. Doesn't trigger spider mines. Costs 50 minerals. The probe has a projectile attack, and is used behind zeals for one hit kills on lings. The probe is the most efficient worker: It can leave buildings to warp in by themselves, so it can mine later. You can do this without management by having the building warp in, then holding shift, and right clicking on a mineral patch or Assimilator.

Zealot(Zeal/Lot/Zlot)
A ground unit, a Zealot channels his enormous psychic powers into creating a plasma shield and energy blades for offensive and defensive purposes. The Zealot is excellent at hand-to-hand combat, and can take a lot of pounding. They can't attack air targets though. The zealot is the most powerful first unit, but it is extremely hard to keep up a supply of them in early game. However, 4 zerglings will murder a zeal. They are best paired with shield batteries and photon cannons to keep the zerglings away.

Advantages:


 * Most powerful base unit of any race in terms of ground attack power
 * A lot of health for a basic unit

Disadvantages:


 * Comparatively expensive to other base units
 * Hard to produce large number in early game without sacrificing economy
 * Cannot attack air


 * Built at: Gateway


 * Cost: 100/0
 * Damage: 16 (8X2)
 * HP: 100/60
 * Supply: 2
 * Range: 1
 * Build: 40

Dragoon(Goon)
A Zealot, after becoming mortally wounded, can volunteer to have its brain placed inside a robotic exoskeleton, and becomes a Dragoon. The Dragoon shoots bolts of antimatter at ground and air targets, and moves moderately quickly. However, it is hard to move large groups of them around, as they are big and bulky. They are prone to clogging up ramps or being surrounded (and slaughtered) by zerglings. The dragoon deals explosive damage, meaning only 10 damage against smaller units like zerglings. That means 4 hits, combined with its long cooldown, makes the dragoon succeptible to zealots, zerglings, and even m&ms (Marines and Medics). However, in numbers, the Dragoon is extremely effective, especially against medium and large units like Goliaths, Hydralisks, Reavers, and Siege Tanks (in regular mode, of course). Even one or two Carriers or Battlecruisers will fall quickly to a large group of Dragoons. For smaller units, however, Zealots are generally better. If used together in numbers, the two can be a deadly combination.

High Templar
Spell-caster: doesn't attack directly, but can use the powerful spell Psionic Storm, as well as hallucinations. 2 can be merged into an Archon. The psionic storm is refered to as the most powerful ability in the game. The psionic storm causes 112 damage to all units (including yours) over the period of 4 seconds. Needless to say, the psionic storm is best used against masses of zerglings or possibly the enemy worker line. Psi storm uses 75 energy- three casts with full energy. While psi storm isn't effective against all units - 112 is not enough to kill a lurker, tank, or even a dark templar or a zealot in one cast - it is still very effective against large amounts of weaker units, like zerglings, hydralisks, any Terran infantry unit, or units with low health.

Advantages:


 * Psionic Storm is powerful
 * Very cheap in terms of mineral cost
 * Hallucination can be an effective distraction if micromanaged properly

Disadvantages:


 * Extremely weak
 * No regular attack
 * Comparatively high cost in Vespene gas

 * Prerequisite: Templar Archives

Archon
The Archon is a psionic entity created via Archon Meld using two High Templar. It is a hovering (does not activate spider mines) melee attack unit against both ground and air based enemies. It possesses 350 shields and 10 life points. Its main attack has a fast attack rate and deals 30 points of damage, making it the third strongest Protoss unit in the game, after Reavers and Dark Templar. Archons can be extremely effective when used in numbers, so if you have a fair amount of minerals and an excess of vespene gas, consider making a number of them.

If you click on a Archon enough and it will say "power overwhelming", a StarCraft cheat code.

Advantages:


 * Archon is basically shields only, so it only takes 9 damage from the Zerg Plague spell.
 * Although not the highest-damaging attack in the game, the Archon's Psionic Blast has a respectably high damage rating coupled with a very fast fire rate, resulting in much damage being dealt in a short time.
 * No matter how badly the High Archon is hit, it can and will regenerate all of its shields, given the time or a shield battery.
 * Creation of a Archon in the midst of a battle from two High Templar that have been exhausted of their energy allows players to get the most out of their High Templar. Beware that Archon Meld takes a while, during which the Archon is vulnerable.
 * Unlike the Dragoon and Scout ATA attacks, the Archon's Psionic Blast is not Explosive, meaning that it deals full damage against small air based units like the Mutalisk. The Archon is the only good air -based counter for Mutalisks.
 * The Archon's splash damage makes it a great weapon to use against stacked enemy air units, and compacted enemy units, such as zerglings.
 * Archons deal linear splash, meaning that all units in the attack path will get damaged. This is probably why the Archon's range is relatively pathetic.
 * Comparatively low cost in minerals - two high templar only cost 50 minerals each, giving it a total mineral cost of 100 minerals, the cost of a Zealot.

Disadvantages:


 * A single hit from the Terran Science Vessel's EMP Shockwave can completely remove all of a Archon's shielding, at which point it has no chance of surviving unless it can be evacuated to safe territory immediately (With 10 hit points, a couple of SCVs could conceveably take it out).
 * Shields do not provide as much protection as standard armor and so the "High" Archon will still take full damage from Concussion type attacks.
 * Irradiate will take an Archon out in about 2 seconds.
 * The Archon has a fairly slow cooldown, so 12 zerglings will mob and kill an Archon with few casualties.
 * Costs a lot of vespene gas for production of large numbers.

Shuttle
As its name implies, the Shuttle ferries other units by air around the map. It has no real other purpose. A shuttle has 8 "slots", explained below- Shuttles are the Protoss' "drop" unit, allowing for drop tactics like the Reaver drop and the Templar Drop.
 * Probes take up 1 slot
 * Zealots and both types of templar take two
 * Dragoons and reavers take 4

Reaver
The Protoss equivalent of a Seige Tank, the Reaver shoots robots called Scarabs which race across the field and explode, dealing a large area of splash damage. Scarabs have a highly advanced tracking system, and are able to navigate around base defenses and friendly units to reach their targets, although at times they get stuck on these, and they also find difficulty navigating around cliffs and other similar environmental obstacles. Reavers are extremely useful against large amounts of weaker enemies; a small group of Reavers situated behind a group of Dragoons or Zealots can make short work of entire armies of Zerglings, Hydralisks, or Terran infantry. Reavers are also the Protoss' "siege" unit, able to attack base defenses from beyond their range. Downside: They move excruciatingly slowly and can't attack air targets, and also require each scarab to be purchased for 15 minerals and a short build time of 7 seconds.

 * Prerequisite: Robotics Support Bay
 * Cost: 200/100-15 per scarab
 * Damage: 100 S (upgradeable to 125)

 * Range: 8
 * Build: 60

Observer
The Observer is a permanently cloaked air unit which can move around and spy on the map. Has no attack. With their Detection ability, observers are Protoss's defense against cloaked units. These are also useful for putting in unclaimed resource areas or other strategic areas (Mountain passes, lookout point, enemy perimeters) to keep tabs on the board. If your opponent doesn't have many detectors, an observer in the enemy base can be valuable, as you will be able to observe (no pun intended) the tech tree being followed and the type of units being built, allowing you to use appropriate counters.

 * Supply: 1

Scout
A light aircraft, the Scout has twin guns under its wings and a pair of missile launchers. Mostly useful against heavy air units. While individually the Scout is not effective against ground units, they do a good amount of damage to them when used in numbers, which makes them good against units that don't have an air attack. The biggest and most debiliatating downside of the Scout is its extreme cost; two scouts cost more than one Carrier in the total amount of resources needed. This considerably limits its effectiveness as a mass attack unit. In general, the Corsair is better against air units, due to its low cost, but the scout is still good against them. Be weary of high numbers of mutalisks, as they will murder scouts.

Carrier
Heavily armored flying machines, they manufacture robotic Interceptors to attack targets. Carriers can hold 8 Interceptors, and are very nasty if used in numbers. They are the best unit to use around shield batteries, as they can still attack when their shields are recharging. Keep in mind: While carriers have greater range than static defenses, interceptors CAN be destroyed, so carriers cannot attack static defenses with complete immunity. Interceptors are healed every time they return to the carrier, or when the stop command is given. A big weakness of the carrier (as well as the Terran Battlecruiser, a very similar unit) is a Ghost with the Lockdown ability; once the Carrier is locked down, it cannot move or attack, making it virtually a sitting duck, so be weary if you happen to spot your enemies using Ghosts.


 * Trick-Have a carrier floating above high ground. Have the carrier attack, but unlike siege tank, the enemy cannot see the carrier when the interceptors are attacking

 * HP: 300/150

Interceptors
Small robotic fighters with limited range which are spawned from Carriers and cost 25 minerals each. They fly randomly and then all rush the target at once and shoot it and disperse. Can easily confuse an enemy as to which one to hit, and seeing tons of these things flying around can have a noticable phsycological impact on a human opponent. The solution, of course, is to attack the carrier, making all of its Interceptors self destruct. Interceptors take 20 seconds to make.

Arbiter
Spell-caster, an Arbiter casts a cloaking field on groups of units underneath it. Its powers are Stasis Field, which freezes enemy units over a large area, making them unable to attack or be attacked - and Recall, which creates a wormhole on any area of the map that units can enter, returning them to the location of the Arbiter. You can't cloak an Arbiter with another one, unfortunately. The arbiter takes a whopping 160 seconds to warp in, tied for the longest unit to build (with the battlecruiser).
