Medal of Honor: Warfighter is a first-person shooter and the sequel to the series' 2010 reboot Medal of Honor. The single-player portion starts with the characters Voodoo, Mother, and Preacher — the latter controlled by the player — all three returning from the previous game as they take on a mission in Karachi, Afghanistan.
