Supernova

Supernova is a StarCraft II: Wings of Liberty mission. Raynor's Raiders tried to collect an artifact before being terminated by a nearby supernova.

Background
Raynor's Raiders were hired to liberate another artifact. Unfortunately, the planet that housed the artifact was right next to a sun that was about to "go supernova".

Heir Apparent
As payday arrived, the Raiders came to the meeting point. As dominion ships warped in, led by Mengsk's flagship, Jim Raynor and Tychus Findlay infiltrated it, Raynor wishing to kill Mengsk. Defeating the marines aboard the ship and getting inside the command room, Raynor did not find Arcturus Mengsk, but his son - Valerian Mengsk. The prince revealed himself as the owner of the, and offered Raynor "a chance to save Sarah Kerrigan".

Aftermath
Valerian Mengsk explained that the artifacts Raynor had been collecting could be merged into a bigger device that could deinfest The Queen of Blades. Both Matt Horner and Tychus Findlay advised Raynor that he not consider taking the deal with the prince.

Gameplay
The player has to get the artifact while a wall of fire is slowly approaching the end of the map.
