Awaken Ancient Machinery (Action): At the end of your Movement phase, one or more NECRONS CORE or NECRONS CANOPTEK units from your army can start to perform this action. Each unit from your army that starts to perform this action must be in range of a different Ancient Machinery objective marker. A unit cannot start this action while there are any enemy units (excluding AIRCRAFT) in range of the same objective marker. The action is completed at the end of your next Command phase, provided the unit attempting the action is still within range of that Ancient Machinery objective marker.

Score 3 victory points each time a unit from your army completes the Awaken Ancient Machinery action.

If the unit performing this action has the Objective Secured ability, the action is completed at the end of your turn; otherwise, it is completed at the start of your next Command phase or at the end of the battle (whichever comes first).

If completed, that objective marker is said to have been awakened by your army.
