Terms Meaning

[Salvoxia]

"Damage" is just an absolute amount without a unit.
Ammunition does a specific amount of damage, which is enhanced by the gun's/launcher's attributes (which in turn are enhanced by skill bonuses), and reduced by the target's resistances for that specific damage type.
To what "points" are you referring?

Thanks for your reply. I mean the points for each kill. like this:

The points are depending on the value of the ship destroyed and are distributed among the attackers based on the percentage of the damage they did. It might be slightly more complicated.
TL:DR most people don't care about points.
