In Day of Defeat gamers team-up to form elite squads for quick strike combat and rugged warfare through historically accurate World War II locations. Powered by Valve's Half-Life technology, the game's multiplayer scenarios drop players into the boots of either a U.S. or an all-new British troop, or a German division of soldiers for intense Allied vs. Axis battles throughout Western Europe. Gamers play as one of several classes of soldiers, including snipers, infantry, machine gunners, riflemen and sergeants, as they are tasked to complete missions and goals unique to each playable battlefield.
