The StarViper is one of four new Wave 6 expansion sets for the X-Wing miniatures game. As with the other expansions in this wave, one of the more interesting things about this wave is that it introduced a third faction: Scum and Villainy.  I have to admit that including these ships in your squad seems a little expensive for what you get (thus the reason for 4 rather than 5 stars), but I still think there are some good reasons to add at least one StarViper to your Scum fleet.
