Combat and system raid last for 20 minutes. Each second fleets inflict damage – 1/1200 of the total attack value of a fleet. 50% of this value is inflicted as damage to ships’ armor and the rest is considered a critical hit and it determines how many ships will be destroyed regardless of armor durability. If a system is attacked by several fleets, the value of their power is added. All fleets that take part in a battle receive damage in proportion to their power. If one party’s fleet power is more than 30 times bigger than the other’s, then this combat ends with minimal loss for a predominant party. In case of combat in space anomalies the same mechanics is used but raid and combat itself go several times faster.
