The first mission in the game is a skippable training mission. The training exercise will guide through the basic controls of your vessel (starting with movement), rotation, and finally combat training.
After some play, you may feel that the controls may not be optimal (especially after playing other modern games such as Half-Life.) The controls can be reconfigured without problem from the main menu, and adjusted to centralize the movement keys in a single area.
At the beginning of the normal campaign, you will be provided with the Pyro-GX.
Motion sickness
Descent 3, like the other games in the series, has been known to cause motion sickness after several minutes of play. If this occurrs, pause the game, and take a short break.
Multiplayer
The multiplayer portion that requires Parallax Online is non-functional.
