An old, but very realistic space shuttle simulator. The package contains, in addition to two game disks, a very thick manual and a large sheet (A2 size, maybe) displaying the cockpit instruments of the shuttle. To successfully fly the missions, the player must learn a great number of dials and how to use every single instrument, located in nine different cockpit panels. The controls can be used with mouse, but keyboard shortcuts are essential for quick operation. In addition to cockpit views, there are various external views, from which you can see the shuttle e.g. in launch pad and in orbit. If you do not use time advance or time skip options during the game, playing one mission can last for days. Going through the proper pre-launch countdown takes five hours, for example.
