This patch is entirely a Combat enhancement patch. It contains the following for the fleet combat:
During combat the player and enemy ships have movement path lines that show you what the direction of the ships path is. For the player the distance shown is fairly long. However for the enemy it is very limited. This was done intentionally as the ability to lengthen the enemy’s path distance will be something you can get later and is tied to a whole new relic system being developed.
There are two check boxes in the upper left corner labeled, Show Player Ship Paths and Show Enemy Ship Paths. By default these are on but can be turned off. If they are off you can mouse over a ship to see its current path. This is true for both the player and enemy ships.
For the player the paths are drawn in green and for the enemy they are red. Fighter Squads have a thinner line than the other ships. If you RMB click on one of your ships a purple line will be drawn from the selected ship to the current mouse position. That let's you know you are changing it and you can see what path that ship will follow. If you LMB click it will set the path and the path will turn back to green. If you RMB click it will cancel the action.
When you select the Mass Aim button then a line will be drawn from ALL your ships to the current location of the mouse. LMB click will set it, while RMB click will cancel. This is a huge benefit while in combat and we’re sure that everyone will enjoy the new feature.
