Adding image to Destroyer 

Nice work, I added one additional cite to round it out, since having footnotes to serious books helps article credibility.

If you want to add an image of the game's cover art, you can do so (with certain restrictions) under WP:Fair use, using the "Upload image/file" link on the left side of your screen, and clicking the options for "Copyight, used under fair use, cover art". Take a look at similar images uploaded for other games to see how it's done.
