This mission is a standing order to attack enemy ships. In terms of battle order, the ship can become an aggressor. This will not affect the way the ship fights.
This mission can be used on any ship, but obviously it makes little sense on freighters.
To behave hostile only to a particular race, set your ship to a particular Primary Enemy, not mission Kill. Kill attacks all enemy races, i.e. everyone you're not allied with.
The "Kill" mission also affects the Glory Device.
Preconditions:
- ship has fuel (otherwise it can't become an aggressor, nor can it fight other ships)
