Missile

Missiles cost 4 turns to build and 4 turns to launch. To launch a missile you also need missile power. The Maximum is 75% which gives you the 100% of the accuracy you would get according to your research, but you can also fire at an reduced amount of power (as low as 30%). The new accuracy of your missile would be described as "Your actual accuracy = The accuracy you researched * (Missile power / 75)"

The EMP missile does no actual damage but instead disables 20% of the enemy's power. Each person can have no more than 75% of their province's power disabled by EMP attacks.
