The CL.II proved extremely successful, with its excellent maneuverability, rate of climb and good armament, allowing it to match opposing single-seat fighters. It was flown by German pilots such as Paul Schwarze and Max Niemann. This is not a complete game. To play, you must own a WW1 Rules and Accessories Pack or WW1 Duel Pack..
