Homeworld: Deserts of Kharak · Unit upgrade
Heavy Vehicles Armor Levels 1–3
Heavy Vehicles Armor upgrades add two armor to AAVs, Railguns, and Missile Batteries. The guide lists Levels 1, 2, and 3 as a progression.
How it works
Level 1 is listed after AAV Fabrication; Level 2 is a later upgrade that unlocks Level 3. The guide repeats the two-armor effect for Level 2 and Level 3 and names the same unit set. It does not say whether each level’s stated amount is cumulative or specify other conditions.
Your next step
Level 2 leads to Level 3 in the listed branch.
