"A massive mechanical human-shaped robot that protects its pilot while it wreaks destruction in its path, the Thor is a master of devastation whether on the sky, or on the ground. With the survivability of a pile of rocks, you can always count on a Thor to take to the front lines and make a big ol' mess out there."
The thor is a huge and powerful terran mechanical siege walker. Despite the thor being smaller than the Odin, the thor is still heavily armed and armored, and known to be one of the most heavy and powerful mechanical units in the Dominion Armed Forces.
Heavy composite neosteel-ceramic armor protects the thor. The plates are modular and can be replaced easily if damaged, or exchanged for thicker versions depending on battlefield conditions. Designed to defeat high-explosive armor piercing rounds, as well as disrupt the searing beams of energy-based weapons, the thor's plating offers unparalleled protection to the pilot and the mech's internal systems. Its innermost layer has a heat-resistant kinetic mesh that prevents damage from shrapnel, slugs, or even sheared armor fragments.ATVX has also developed an "immortality protocol," allowing a thor to repair itself in the field as long as its hull remains intact.
The thor's cockpit is pressurized and protected by a military-grade steelglass canopy, as well as thick layers of composite neosteel-ceramic armor. At its center lies the pilot's seat, which helps prevent operator injuries through powerful inertial dampeners and a foam-padded six-point harness. Multiple gauges and screens monitor the mech's systems, and the main holographic display projects computer-generated imagery of the terrain. Were this screen to fail, the steelglass canopy has a fully integrated heads-up-display, a navigation screen, and a basic targeting system.
Improving the Thor has become somewhat of an informal competition amongst Terran Dominion engineers. The Dominion's top brass is content to allow this trend to continue, as it results in more powerful siege walkers. Meanwhile, improvements in neosteel plating and innumerable upgrades made the thors of the Dominion Special Forces a signature achievement in weapons engineering. The Knights of Tyrador designed a thor variant with plutonium coating that deflected projectiles under a certain energy threshold, which also made them look good in parades.
The thor is equipped with different types of heavy weapons, and has enough artillery to take down an entire enemy army by itself. It is armed with four "Thor's Hammer" particle accelerators (two are fired from each arm). Originally, four 250mm strike cannons resided on its back, but these have since been replaced by Punisher cannons. These fire 250mm anti-aircraft shells fitted with advanced electronics to minimize wasted shots. Their depleted uranium cores allow them to punch through the plating of heavily armored aerial targets, causing serious damage. Each shell is individually chambered by a basic auto-loading mechanism that simplifies maintenance and repairs. The cannons' rate of fire is capped to avoid malfunctions and to extend the service life of the ordnance. Bypassing the limit is not recommended, as the cannons may melt or explode.
For aerial opponents, the thor is equipped with Javelin missile launchers. These are located on both sides of the steelglass canopy, and fire four small, IFF fragmentation warheads that can rip through multiple, lightly armored aerial targets on a single salvo. Due to the missiles’ small size, the thor can carry a large payload, ensuring it will be fully prepared to deal with groups of flying bogeys even in drawn-out engagements.
The thor can be optionally outfitted with 330mm barrage cannons.
The thor stemmed from the Terran Dominion Thor Project, a program that resulted in the creation of the Odin. When the thor made its public debut, military analysts were stunned, and embedded UNN reporters described it as "a huge bipedal war machine armed with a dorsal artillery that wouldn't be out of place on a battleship." Thors were being used in the field by 2502.
Chief Engineer Rory Swann reverse-engineered a schematic of the thor from examining the Odin prototype. He refined a design that had millions of credits of R&D poured into it. His efforts focused on making it cheaper. The Raiders received their first thors during the attack on the UNN Studios. At the time, he stated that his design still needed some work on the chassis, but had some ideas for upgrades and variants. While still unavoidably expensive for Raynor's Raiders to produce, Swann considered the addition to their arsenal to be worth it.
The thor can be transported by the Hercules dropship and medivac dropships. One thor fills up the medivac's entire capacity, transforming into a cube-like shape and hanging from underneath.
As of StarCraft II: Heart of the Swarm, the thor can switch between Javelin missiles (which destroy light air units) and Punisher cannons (which are single-target attacks designed to take on powerful air units).
A thor's primary role is to act as the spearhead: a big tough unit that can push past an artillery barrage or fortified positions or push into an enemy base and lead marines into battle.
Its other primary role is to defend allied units from air attacks with its powerful anti-air weaponry. It works well against light air units like mutalisks, but the attack is not as effective against heavily armored air units such as battlecruisers. The thor is one of the only terran units that can withstand a single nuclear missile strike besides battlecruisers. Thors and Vikings is unstoppable against any air power, Thor’s focus down on light air targets while Vikings destroy armored tougher targets.
The thor is countered by range, mobility, and certain anti-armor units. It doesn't deal splash damage to ground units, therefore, it cannot effectively deal with massed units such as marines, zerglings, and zealots. Thors should also avoid marauders, void rays and immortals due to their bonus damage against armored targets.
A popular strategy with the unit is the "thor harass" (sometimes called "thorship"), similar to the reaver harass of StarCraft. It involves pairing the thor with a medivac dropship, combining the thor's power and the mobility of the latter.
Some features that existed on the thor in previous builds led to a concern that its role was overlapping with that of the siege tank. Unlike the siege tank, the thor is an assault unit rather than a siege unit. Its ground attack has much less range than a siege tank's 180 mm cannon, so it is exposed to enemy fire while attacking.
Another difference from the siege tank is that the thor can also function as a ground to air attacker.
Thors, Vikings and siege tanks is also an unstoppable combo using long range to destroy anything that opposes them.
The thor attacks an enemy ground unit or structure using the cannons on its back. The target unit is stunned for the duration and takes 500 damage. The thor cannot move or attack when using the ability.
A "destroyed" thor becomes a structure with 400 hit points and 1 armor. The structure may be restored into a functional thor if not destroyed. The restored thor returns with the structure's remaining hit points.
ATVX now offers an updated thor model that can repair itself to full working condition if the hull remains intact. This repair process is a fraction of the cost of building a new thor, and it allows you to quickly reactivate a thor that is destroyed in the field.
Upgrade's thor's strike cannons to deal 500 splash damage over a large area. Stuns targets in center of blast.
The 330mm Barrage Cannon is the final word in siege-walker technology. This massive battery of dorsal cannons can lay down a sustained barrage that will pulverize most defenses and annihilate all ground targets in the area.
Attack upgrades improve attack cooldown of affected units by 5% per level.
These self-replicating ultra capacitors reduce the reload time of weapons and systems. Now each of the weapon upgrades at the armory and engineering bay increases attack speed by 5% in addition to increasing damage.
Armor upgrades increase health of affected units by 5% per level.
We have created a new lightweight alloy called vanadium. Vanadium diffuses weapon impacts much more efficiently than traditional armor plating, and it better preserves the life of our units. Now each of the armor upgrades in the armory and engineering bay increases unit life by 5% in addition to increasing armor.
Damaged mechanical units recover hit points when out of combat, at a rate of 0.6015 each second.
Our ship and vehicle hulls are now made from a material called Regenerative Bio-Steel. This material uses internal nanobots to slowly repair any damage the hull sustains. While this regeneration process is much slower than conventional SCV repairs, it can be the difference between life and death if no SCVs are available.
Increase starting energy of all units by 100. Increase maximum energy of all units by 100.
This reactor has a larger energy reserve on startup and can hold a much larger charge. Now our specialist units can use their abilities the moment they hit the battlefield, and they can store more energy when idle for long periods of time. All "Specialists units" use energy: such as the medic, ghost, spectre, thor, wraith, banshee, raven, science vessel and battlecruiser.
Walter Simonson is a comic book writer and artist who famously worked on the Marvel Comics title The Mighty Thor. It appears the Simonson Munitions Factory was named after him. Simonson is also one of the authors of the World of Warcraft comic series.
A new version of thor, named the "Super Thor," appears instead of the standard version in the Collector's Edition of StarCraft II: Wings of Liberty. It is identical in terms of gameplay. The Collector's Edition also offers a mini-thor pet for World of Warcraft that is capable of flight. The "Super Thor" was reused in Heart of the Swarm for the Blackhammer.
In the game files the thor can be found dancing. He seems to be an expert at "doing the Robot".
In Norse mythology, Thor is the son of Odin. This is reflected in the StarCraft lore where the thor is derived from the Odin prototype.
The thor, within the scope of Wings of Liberty, is supposed to have been developed by Swann. This contradicts Thundergod, and Wings of Liberty. Blizzard has acknowledged the error as the result of two internal teams working on the same piece of lore.
