Existing/Updated Terran Buildings
• Armory
• Barracks
• Bunker
• Command Center: Has the ability to carry up to five SCVs and can upgrade to the powerful armed Planetary Fortress.
• Engineering Bay
• Factory
• Missile Turret: The Missile Turret loses its detector ability and relies on the Sensor Tower to grant it detection.
• Planetary Fortress: This upgrade of the Command Center greatly increases its power and grants it weapons to attack enemy units with.
• Refinery
• Starport: The Starport can be upgraded into a permanently flying Star Base.
• Supply Depot: The new Supply Depot can submerge, enabling troops to walk over it. It is smaller and can be made into an important part of Terran base defenses, preventing enemy units from walking past them.
• Surveillance Station: This upgrade of the Command Center enables scanning of troop movements through the fog of war.
New Terran Buildings
• Deep Space Relay: This structure allows production of Battlecruisers and provides researches for them.
• Merc Haven: This structure produces Reapers.
• Munitions Depot: This structure allows production of Thor by SCVs and provides researches for them.
• Radar Tower: This building can sense enemy units, even if they are moving in unexplored terrain. However, enemies can sense its location and scanning radius. It is an upgrade of the Sensor Tower.
• Sensor Tower: This structure enhances detection by granting it to Missile Turrets. It can be upgraded to a Radar Tower.
• Shadow Ops: This structure enables Ghosts to be produced and provides researches for them. In addition, it stores nukes and Drop Pods for launch.
• Star Base: This permanently flying structure is an upgrade of the Starport. It produces units despite flying and can "re-arm" nearby units (increasing their energy pool).

Add-Ons
In StarCraft II, Terran add-ons work quite differently. There are only two add-ons which have been described, the Nuclear Reactor and the Tech Lab. Instead of being specific to an associated structure, each add-on can be added to any Terran unit-producing structure (Barracks, Factory or Starport), granting a specific benefit. One structure may only have one add-on attached to it, so it cannot benefit from the Reactor's bonus and the Tech Lab bonus simultaneously.
• Nuclear Reactor: When added to a Terran structure, this doubles the number of units produced from a building. (For instance, adding one to a Factory will enable it to create two Vikings at the same time.)
• Tech Lab: When added to a Terran structure, the Tech Center enables that structure to produce "higher tech" units. For instance, adding a Tech Center to a Barracks will allow it to produce Medics, while adding one to a Factory will enable it to build Siege Tanks.

AW man the Science Vessel was relley useful

yeah it did have its advantages..o well

nice sig btw

thanx man. i made it. it pwns all.

yeah i didnt read any of this. i just want to comment because i am the terran posting ninja in this site. good day to you all.

Ya know, I'm actually looking forward to playing with Terran this time. Surprising because I hate Terran in the first game. Probably 'cuz I'm not very good at micromanaging. There are two things which I really want to try as Terran. Well...more than that, but the two main things are sinking supply depots, and plasma turrets on the bc.

I think that Terran were the strongest race in the original Starcraft as they had medics which could heal you portably and tanks and pretty good air... they were good in all fields ...

I can't wait for Starcraft 2 to come so that i can play with the new Terran... its taking so sooo long to release this game... I hope its worth the wait but it looks like it is so far...

star base? wahahaha, how would it look like?

reactors sweet terrain rush

Medics and Firebats are not returning, they're only gonna be in single player and in the map editor. Along with all the other original/canceled StarCraft units.

At this point in the SC2 beta terrains are very underpowered, ive heard blizzard is looking into this to fix shortly, very sad day.

Terrans against zerg seem underpowered howver against protoss they stand a chance because of ghosts.

It's gonna be awesome seeing if there will be any WC units.
