Giant Clank encountered three of vessels while traveling through The Quasar Fields of the Delta Sector. The first two vessels will fight for several minutes before they retreat, while the third vessel will stay and fight for; however, long the battle goes. Thus its possible to only expend time killing the third MegaRock Class Dreadnought while ignoring the first to vessels. However, players should attempt to destroy all three vessels, which earns the Skill point I Kill The Rock.
