Thor

Thor is a Terran mechanical unit which is named after the Norse god of thunder. Despite its intimidating appearance, it is not a super-unit; and more than one can be built.

Lore
The Thor project was the most significant Terran Dominion military development since the Brood War. It was developed at the Simonson munitions factory on Korhal under a complete security lockdown; the workers were effectively all under arrest to prevent any leak of information. As the project came closer to fruition Umojan Protectorate spies observed an increasing flow of high-ranking Dominion officers coming and going from the plant. Their hacking of cargo manifests showed deliveries of battlecruiser-weight neosteel armor and their sensors showed regular seismic shocks. Nonetheless, their information was extremely limited. Umojan agent Ulli Trey sneaked into the facility and, using an array of stealthy drones, finally acquired the information the Protectorate had sought; the secrets of the Thor Project were bared. The Thor, armed as heavily as a battlecruiser, could be constructed quickly by SCVs in the field. The Protectorate feared that no counter to this weapon would be discovered.

Thor is armed with a pair of "Thor's Hammer" Particle Accelerators and four 250mm Bombardment Cannons.

Game Unit
Thor is not built through a building, but rather it is built by SCVs, due to its large size. Thor has a relatively immense size when compared to other units and vast reserves of hit points. It has a long firing range and big splash damage and a long cool down. It is weak to air attacks and it is slow and takes a long time to turn around to flee or target enemy units; thus leaving it vulnerable to hit-and-run attacks.

Thor has a weak anti-air attack. It is not vulnerable to anti-air attacks like a Colossus.

Thor has six weapons (two arms and two on each shoulder). Originally it was thought that each shoulder weapon fired independently (misunderstood from a picture of Thor firing his shoulder weapons, if you look closely you can tell that both are indeed firing), but now it has been revealed that Thor's shoulder weapons simply alternate firing during it's 'Artillery Strike'. It can do area of effect damage over a long distance using the 4 cannons. The Artillery strike costs energy.

Thor is too large to be transported, but the SCVs that build it could be transported, therefore opening new strategies for building the Thor in secret locations.
