Ground combat
When troops arrive through a portal, a ground battle pits both sides' armies against each other. Doctors heal part of the losses.
Ground combat sequence
A ground combat is triggered when a portal Attack mission reaches its target. The sent troops (attacker) face the military populations and combat equipment present on the planet (defender). Combat is simulated instantly from the statistics of both armies.
▸ For the curious Force calculation
Attack power (damage)
For each military unit:Damage = nb × base_damage × tech_bonus × (1 + boost)
Vehicle boosts (Hauler) apply on top.
Total force is the sum of all unit damage.
Defense power (resistance)
For each military unit:Resistance = nb × base_resistance × tech_bonus × (1 + boost)
Includes all military units present on the planet.
Total force is the sum of resistance of all units.
Doctors — loss recovery
After combat, doctors heal part of their side's losses: healed units are not lost (populations and equipment alike). The healed share is not a fixed percentage per doctor, but depends on the number of doctors relative to the size of the army.
Formula
Ratio = equivalent_doctors / frontline_unitsHealing = 50 % × Ratio / (Ratio + 0.1)Healed units = losses × Healing (rounded down, for each unit type)
Where:
- Frontline units: soldiers, commandos, snipers and combat equipment (Avenger, Guardian, Hauler…). Doctors are not part of them.
- 50 % is the maximum healing, never reached. 0.1 is the ratio at which healing equals half of the maximum, i.e. 1 doctor for 10 frontline units.
- Doctors do not fight (no damage, no resistance), but they take losses like other units and can be healed too.
Example: 100 000 frontline units and 10 000 doctors → Ratio = 0.1 → Healing = 25 %. If 30 000 units are lost, 7 500 are healed.
Guardian boost
Each Guardian boosts the healing efficiency of 50 doctors by +30 %.
Example: 1 000 doctors and 10 Guardians → 500 boosted doctors → 1 150 equivalent doctors.
