Long Range Fire
Naval units, land units with the Heavy Artillery ability and Spore Launchers may conduct Bombardment by selecting the Long Range Fire option from the Action menu.
Bombardment has the advantage of potentially damaging every enemy unit in a particular square and the disadvantage that land units can never be reduced below 50% damage by bombardment.
If a unit is bombarded it will not heal for the turn, it will also cancel a former's terraforming
If bombardment is attempted against a square containing an enemy naval or artillery unit, the bombardment is canceled and an Artillery Duel is initiated, with the attacking and defending artillery (or naval) units fighting attack-vs-attack strength. Armor values are ignored for Artillery Duels.
Bombardment may also be used to destroy square improvements (Xenofungus cannot be destroyed by bombardment)
