Target Lock is one of six standard Action Bar actions that a ship can take, available on most starships.
The action requires targeting an enemy ship within Range 1 - 3. A red Target Lock token is placed next to the target ship and a matching blue token is placed next to the ship taking the action.
Target Locks may be spent after rolling attack dice to allow any number of them to be re-rolled. A number of Secondary Weapon Upgrades also require a Target Lock to be spent before they can be fired.
