EngineeringBay SC2 Rend1

The engineering bay

The engineering bay is a terran building used to improve the quality of weapons and armor fielded by infantry.[1] They were in use by the Terran Confederacy as early as 2488.[2]

Overview[]

Within the Dominion Armed Forces, whenever a strike force is deployed planetside, the engineering bay is one of two key research facilities to be established in a field base as soon as possible (the other being the armory), improving the quality of infantry weapons.[3] During the Great War, these structures were equipped with the ability to lift off and move to a new location. However, after the Brood War, the engineering capabilities were improved, increasing the personnel of the structure and intricacy of their work. Because of this, engineering bays were no longer cleared for flight.

The Dominion Special Forces utilize AIs in their experimental engineering bays, which increase their research speed by fighting each other in simulated battles. Meanwhile, a portion of the Knights of Tyradors engineering bays are utilized in researching new amusement park attractions, though this was temporarily suspended after the Battle of Tyrador IX.[4]

Game Structure[]

The weapons plant

The weapons plant was a terran structure in the StarCraft beta. It was cancelled before the game's full release.[5] It was later turned into the engineering bay.[6]

StarCraft II[]

Versus[]

The engineering bay reappears in StarCraft II. It can no longer lift off.

Wings of Liberty[]

In the Wings of Liberty single player campaign, the Hi-Sec Auto Tracking and Building Armor upgrades are not available, while the Neosteel Frame upgrade to bunkers is an upgrade purchased in the Hyperion's armory.

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.

Vanadium Plating

Armor upgrades increase health of affected units by 5% per level.[7]

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.

All structures repair themselves to 50% life. All structure fires are automatically put out.

This all-in-one safety system automatically dispatches robotic drones to put out any fires and perform basic repairs on damaged structures. Although these drones are effective at doing basic repairs, they do not have a strong enough AI to perform the more delicate repairs needed to restore a structure past half life.[8]

Co-op Missions[]

The building is available to Jim Raynor, Rory Swann, Nova Terra, Mira Han and Matt Horner, Tychus Findlay, and Arcturus Mengsk, however each variant has unique upgrades available for research.

Notably Swann and Han and Horner's engineering bays do not give them infantry weapon or armor upgrades; the building gives Swann defensive turret and building upgrades only, while Han and Horner gets special upgrades for Mira's infantry units instead. Han and Horner weapon and armor upgrades are provided at their armory instead. Alexei Stukov has access to a infested engineering bay which can upgrades infested infantry and infested bunkers.

Development[]

As of patch 4.7.1, Neosteel Frame and Structure Armor were merged into an upgrade called Neosteel Armor.

The StarCraft II engineering bay was designed to be a more simple structure than its predecessor. It was decided to make it a grounded structure as per the belief that only unit-producing structures should be able to lift off.[9]
