In General

The Engineering Bay houses the engineering team, headed by Dr. Shen.

Build/Buy Items

Here you can build or purchase items that you have the resources for.

Item Fabrication Capacity

The Engineering Bay grants an item fabrication capacity of 2. This means you can produce a maximum of 2 different item orders simultaneously. All other item orders will be queued to start once they finish. The item fabrication capacity is increased by 1 for every workshop.

Rushing

Rushing the production of an item reduces the base build time by 80%. The cost is 40% more resources and 5 meld.

Due to number of engineers affecting actual build times, when rush building, the final build time will likely not decrease by a full 80% (Click here for more info: Scientists and Engineers)

Repair Bay

Items can be damaged when a unit is wounded during a battle.

They require 80% of their original build time and 50% of their original build cost to repair. Repairing does not affect item fabrication capacity.

Augment Soldiers

Augment up to 1 soldier at a time to become a MEC. For more information click here: MEC Augmentation
