This trailer features in-game footage from an early build of DCS: P-51D Mustang, the upcoming World War II aerial combat game from Digital Combat Simulator. Here's a bit on what to expect from the game: "The DCS: P-51D Mustang offers both highly-detailed simulation and easy-to-play "game" mode options for both hardcore and casual gamers. When in simulation mode, this is the most authentic simulation of the P-51D Mustang that has ever been done for the PC."
