Ace type enemies should be introduced, they can be shot down to unlock nicknames, emblems, credit bonuses, research bonuses, supply tickets or even skins.

There are 5 different aces for each map, with only one appearing at a time. They are extremely mobile and have more HP than their regular counterparts. They spawn very rarely.
