Combat Ratio

The ratio between your fleet power and the recommended or enemy power. Influences combat risk and expedition survival.

Combustion Technology

Research that increases fleet speed and reduces travel time.

D

Debris Field

A resource field created when ships are destroyed in battle. Can be collected using Cargo Ships.

Debris Rate

The percentage of destroyed fleet value converted into debris.

Base Rates:

PvP: 30%
Pirate Battles: 40%

Modified by:

Salvage Operations research
Realm reductions

Depth

The progression layer within an expedition. Each deeper level increases rewards and risk.

E

Energy

A required resource for mine production. Negative energy reduces mine output.

Espionage

The act of scouting another player or pirate using Probes to gather information.

Expedition

Fragment

A rare item used for research, blueprints, or special unlocks.

G

Gas

A resource required for fleet fuel and advanced research.

Galaxy View

The interface where players scout systems, send fleets, and access Nebula Centers.

I

Imperial Credits (IC)

A special currency used for Trade Center offers, battle simulations, and Imperial features

L

LOG2 Scaling

A logarithmic scaling formula used in expedition discovery calculations.

Example:

Discovery Chance = MIN(LOG2(probeCount), 10)
