EMP Damage
EMP damage is caused by EMP turrets or residual EMP zones.
Units affected by EMP damage are considerably slowed down (if mobile), have extremely reduced attack and scanning ranges, and cannot perform operations (e.g. terraforming).
The effect is worse the higher the level of existing EMP damage, but shows the biggest difference between 0 (no damage), 1, and 2.
EMP damage does not stack, and heals by one each round.
