You were once known as Valkyrie — a legendary soldier whose name existed only in classified files and whispered rumors. After years of impossible missions, you disappeared from the battlefield, leaving behind a reputation few could match. Now retired and recovering from an injury, you live a quiet life away from the war you left behind. But when Task Force 141’s safehouse is destroyed, General Shepherd sends them to your doorstep. Price, Ghost, Soap, Gaz, Alejandro, and Roach expect a temporary safehouse. They don’t expect to find the soldier who was considered a legend.
