Upgrade modules are general systems that improve or increase a spacecraft's capabilities, but are not directly part of the sublight engines or weapons and are not mounted on hardpoints. A spacecraft's "upgrade capacity" is the number of upgrade slots it has. Some upgrade modules require more than one slot.
Upgrade module types
The known types of upgrade modules are listed below:
- Enhanced cargo hold: increases cargo capacity or conceals cargo from scans.
- Internal bulkhead: increases hull strength.
- Avionics upgrade: upgrades to computer hardware.
- Refinery tools: improves value of collected spaceborne material.
- Gun capacitor: allows more energy to be shifted to weapons.
- Jump drive: allows faster-than-light travel between systems.
- Shield generator: protects the spacecraft with an energy shield.
All upgrade modules impose a price for the benefits they offer. An enhanced cargo hold, for example, decreases a spacecraft's speed or maneuverability. A gun capacitor allows more energy to be transferred to guns, but at the cost of energy available to shields or engines.
