Trade resources are a type of resource found on planets. They can be traded to other empires. Trade resource tiles can be destroyed to make room for other improvements. Crusade overhauled the resource system, including trade resources.

Trade Resources in Crusade

In Crusade, trade resources accumulate at a rate increasing with the level of the resource tile improvement, which also gives intrinsic bonuses. Resources can be spent on improvements, citizen promotions, and shipyard missions.

There are two main types of trade resources: mined and harvested. Each type has three levels of extraction, gated by specific technologies. Improving mines to Level 2 requires the Unrecognized icon nameGC3 Productive Ability Icon Xeno Resource Mining, and Level 3 requires Unrecognized icon nameGC3 Productive Ability Icon Advanced Resource Mining.

Trade Resources in the Base Game

Bonus to Adjacent Improvements

Each trade resource on a planet provides an adjacency bonus to surrounding tiles.

Player Achievement Bonus

Each trade resource has a bonus associated with owning the resource. This is a global bonus that applies to your entire civ. The bonuses do indeed stack (despite the tooltip when looking at the resource saying "One Per Player") so owning 2 Precursor Nanites, for example, will give you a global +10% to your manufacturing on all of your colonies.

Note that if you trade a resource away to another civ and then lose your access to that resource, the civ that you traded the resource to continues to receive that resource until the number of turns expire, leaving you with a negative number of that resource. You do not receive any penalties from having a negative number of trade resources. There are several ways you could lose access to a trade resource:

  • Destroy the trade resource on the colony screen of one of your planets.
  • Give away or lose a planet to another civ.
  • An agreement from another civ granting you the trade resource expires.
