Research and Tech Trees

The three research trees, the buildings that unlock them, and the HQ and Armory levels and Familiarity that gate the deeper nodes. The spine of all progression.

At a glance

The spineA research tree split into three trees, fed by research over time at a Research Station.
Tree 1Base and Buildings, unlocked by a built and powered Communication Hub.
Tree 2Weapons and Equipment, also unlocked by the Communication Hub.
Tree 3Alien Research, unlocked by a Laboratory with clean water.
The gatesHeadquarters level, Armory level, and Familiarity with fauna, flora, and materials.

Everything flows from research: better towers, better mech weapons, better energy, environmental protection, and access to rare resources.

The Familiarity gate

Most Alien Research nodes need Familiarity with specific fauna, flora, or materials first. You gain it two ways:

  1. Kill or destroy creatures and structures, which can drop DNA Fragments the mech collects.
  2. Use the Bioscanner (from the Laboratory) on green-highlighted entities, which grants DNA Fragments more reliably.

Some Alien Research nodes are also locked behind Campaign story missions, including environmental shieldings and certain special structures and floors.

Do this in order

  1. Build and power the Communication Hub to open the Base and Weapons trees.
  2. Build the Laboratory (clean water) to open Alien Research and the Bioscanner.
  3. Prioritize extractor and resource upgrades early. A Tier 3 Extractor effectively quadruples deposit output.
  4. Research the environmental shielding you need before entering a hostile biome.
  5. Keep Headquarters (levels 3 to 7) and Armory (levels 2 to 5) upgraded so deeper nodes stay available.
