B-17 Flying Fortress: The Mighty 8th

Feel the power of flying a real B-17! See what it was like to be part of a 10-man crew on dangerous bombing missions over occupied Europe. Realistic graphics, animations, and sounds convincingly recreate every aspect of the strategic air battles in WWII. Twenty five scenarios, in which you must manage your crew’s strengths and weaknesses, test your pilot and leadership skills. This is your team, they are under your command, and it is your job as a captain to complete the mission and take them home in one piece. This game is a real gem amongst other simulators. With impressive attention to detail and historically accurate missions you can really feel like you are fighting in WWII. Control any of ten different crew positions, seeing the combat as a pilot, one of the gunners, or a communications officer. You can also fly one of the escort planes like P-38 Lightning, P-51 Mustang, and P-47 Thunderbolt. In addition, you are able to switch sides and fight against “The Mighty Eighth” taking the role of a German Luftwaffe pilot and find out first hand why the B-17 bomber codename was the “Flying Fortress”. Become a crew member, in any of ten crew positions, of one of the most powerful and deadly machines of WWII – the B-17 Flying Fortress. Over 25 realistic missions, based on real historical events, in which you must lead your crew to victory. Impressive attention to detail, terrific flight and damage modeling, and historical accuracy give this game a really high educational value.
