Starshatter includes three different flight models so that you can enjoy the space combat experience in the way that is most effective for you.
By default, Starshatter is configured for the "standard" Newtonian flight model. In this flight model, all ships have both linear and angular momentum or inertia. There is no drag in space, so if you cut your engines to zero you will keep going at your current speed indefinitely. Your onboard flight computer will try to keep your velocity pointed in the same direction as your nose, but you can turn off this behavior by pressing "M" for manual mode. In manual space flight mode, you can fly sideways or backwards to your heart's content.

In the standard flight model, airborne combat is quite similar to what you will find in a good jet combat simulation. Your fighter will fly just like an airplane, with lift, drag, gravity, angle of attack, and atmospheric density to contend with. You have very limited rudder authority, and you have to perform banked turns at corner velocity to stay in the fight.

In the arcade flight model, Starshatter is much more like what you may be used to from playing other space combat simulations. Your ship always flies in the direction you are facing, and your throttle setting controls your speed instead of your acceleration. If you cut your throttle to zero, your ship will slow to a stop even in space. You can perform flat turns in atmosphere, and you don't have to worry about drag or stalls. Gravity is still modeled, and you do still have to worry about running out of fuel and slamming into that big hard thing called "the ground."

Starshatter even includes a "relaxed" flight model that is between these two extremes. The relaxed model is similar to the standard model except that drag applies even in space. This helps keep your velocity under control, and makes it easier to turn.

One way or another, you should have no problem finding a flight model that works for you. Now get out there and start getting us some kills!
