Next Terran Unit: Viking
Previous Terran Unit: Siege Tank
The Thor project has been shrouded in mystery since its inception. Agents of the Umojan Protectorate were the first to investigate the Dominion’s new terror weapon. Images from this investigation showed a huge bipedal war machine armed with a dorsal artillery battery that wouldn’t be out of place on a battleship. Most disturbing of all was the discovery that this monster could be built rapidly from the ground up by a standard Factory.

Units
Thor
Driver’s Handbook
- Massive armored unit that can attack both air and ground targets.
- Its main cannons deal heavy damage to all land-based units and structures, while its missile launchers keep enemy air forces at bay, especially Mutalisks.
- Very vulnerable without support.
- Slow-moving and costly to produce. Combine with SCVs for field repairs, and Medivacs to ferry them quickly across the battlefield.
- Equipped with powerful 250mm strike cannons that incapacitate the target and deal 500 points of damage over the course of 6 seconds. This weapon can be fired against ground units and structures (best used against enemy Thors, Ultralisks, or Colossi).
Countermeasures
VS Terran
- Tanks in Siege Mode with infantry support are a great way to eliminate Thors and their escort.
- Cloaked Banshees allow you to attack on your terms; try to catch the enemy on the move and beware of Scanner Sweeps.
- Assemble a large force of Marauders and focus fire. Works best if you research Stimpacks and build a few Medivacs.
- Use Battlecruisers, and especially their Yamato Cannon, against Thors.
VS Zerg
- For the most part, large groups of smaller units work better against Thors. Try to attack from different directions simultaneously and don’t forget to focus fire.
- Use Zerglings to support your Roaches or Hydralisks. Be sure to research Metabolic Boost, Tunneling Claws, and Grooved Spines.
- Infestors can take over a Thor using neural parasite, turning the tide of battle in your favor.
VS Protoss
- Immortals excel against Thors due to their Hardened Shields and high damage against armored targets.
- Employ a large force of Zealots and Dark Templars to surround them. Be sure to have the Charge upgrade for your Zealots and to designate a Thor as your target. If you use attack move, your units will charge the escorts.
- Use the High Templar Feedback ability to drain their energy and deal instant damage. This will prevent them from using the 250mm strike cannons.
- Void rays work well against Thors.

I like the Norse mythological connection. And I think many other sc2 players are also happy that their ancient religion and culture is refered to such a great game.
But Irish...nah author must have made a typo or something..? Celtic religion is indeed something entirely different.
Immortals are the best counter-units to Thors. Yes, thors take out immortals with their 250mm strike cannons, BUT, the fewest ones are going for that uppgrade. Besides, protoss will normally have more immortals than Terran has thors, atleast in mid-game, therfore unless thors are support by SCV's or you are great microer or your thors stand on a cliff where immortals lack vision, your thors are doomed. Trust me, I use them pretty often. Also if you uppgrade their shields or cannons, they might just about stand a chance against immortals, assuming you have made uppgrades to 3 degree.
He's at a rave! :D
how outdated
What, it needs max graphic setting or what?
"Use the High Templar Feedback ability to drain their energy and deal instant damage. This will prevent them from using the 250mm strike cannons. "
I think the thor doesnt need energy anymore to use their ability. Blizzard, please keep up with your own changes :p
