Heavy Engineering Depot

The heavy engineering depot constructs tanks and other armoured vehicles, and is also required to research Fortification and Construction upgrades.

Notes:

• You must have researched Stainless Steel (Metallurgy Level 1) at the Foundry.
• Units here have a ramp cost of 3-4 oil each.
