Death Angel

Death Angel is a rare but dangerous creature. Death angels' ethereal bodies make them difficult to spot until they're close enough to kill you. They emit energy blasts that can level the strongest base structures in moments. Lasers and other conventional weapons are effective against them. The trick is destroying the angels before they can destroy your weapons. Death angels do not appear in any of the main game missions. They are found in a few of the Galaxy Mode missions and can be included in user-created levels.
