Line of Sight

Line of sight is how far a unit can see. Because all units have active camouflage they can't be seen by the enemy at long range, only when they are in the line of sight of one of the enemies units. Some units can Cloak, they can only be seen by the enemy when in the line of sight of a unit that can detect cloaked units.

There are 3 layers of visibility in Achron. One of them is basically not used.
