Since Ancient Galaxy uses a 3rd person perspective, the camera's position is behind the player character's head but you can further modify its placement vertically (low, middle, high, top) and horizontal (left, center, right, smart).
The Smart Camera setting is an aggressive active camera setting designed to increase your immersion sensation.
Furthermore, you can adjust the camera's proximity to the player character's head/shoulders by choosing the Camera Zoom Level: close, medium, and far.
Ancient Galaxy provides basic stereo sound. You can optionally adjust stereo panning and separate music volumes as well as the master volume.
Supports all DirectX 9 compatible video cards with at least 256 MB of memory. Integrated graphic display chipsets, such as Intel, should work but will be slow (for these systems it is strongly recommended to use lower resolutions without anti-aliasing).
Resolution: Ancient Galaxy provides standard display options ranging from 800x600 to 1280x1024.
Anti-aliasing: the more samples the greater the removal or distortion artifacts. Anti-aliasing can be turned off (recommended for integrated graphic chipsets), 2 sample rates (2xAA) can be applied, as well as 4 sample rates (4xAA).
Brightness: also known as gamma, can be adjusted to affect how everything appears.
Your game progress will continually be automatically saved without requiring consideration. Additionally special save points throughout the game will also be recorded in case you would want to Revert Progress.
There are three setting available at the bottom of the main menu which take effect instantly. The default is Normal. The other choices:

Hard: increases the damage you receive by 100% and decreases the damage your weapons do by 75%. It also decreases the auto-aim feature of your guns by 50%.
