From Fantasy Flight Games (www.fantasyflightgames.com):
When they appeared in the sky, they changed the course of history! Giant airplanes, with a wingspan larger than that of a WW II Flying Fortress, were already flying during World War I and able to reach strategic targets, leaving their mark on the course of the fight. Now, you can board and fly these giants of the sky towards their target…
Flight of the Giants is the first expansion set for Wings of War, introducing into the game early bomber planes, with new rules to handle their extended crews and fighting capabilities. You can now maneuver a huge Zeppelin Staaken, a Friedrichshafen G.III, or a Handley Page O/400, avoiding the fire of enemy fighters and searching for your target. Flight of the Giants features 8 different bombers of the Allies and the Central Powers, such as the Felixstowe F.2A, Zeppelin Staaken R.VI, and Caproni Ca.4!
Flight of the Giants is not a complete game. A copy of at least Famous Aces, Watch your Back!, Burning Drachens, or WWI Deluxe is required to play.
