"Alex and Grig attack the Ko-Dan mothership, crippling its communications. Once Alex's weapons are depleted, he desperately activates a secret weapon on the Gunstar, the "DEATH BLOSSOM", that destroys the remaining Ko-Dan fighters. With the fleet destroyed, Lord Kril orders Xur executed for his arrogance and failure to ensure victory, but Xur escapes the mothership just before Alex cripples its guidance controls, causing it to crash into Rylos' moon."
