The Windows version of Jade Empire is known as the 'Special Edition'. It is based on the Xbox 'Limited Edition', and also includes the Monk Zeng character but not the Tien's Justice weapon style (both of which are available in the Limited Edition described above). Changes from the Xbox version includes increased resolutions up to 1600x1200 (1920x1200 in Widescreen), new special effects and redrawn textures, two new martial styles (Iron Palm and Viper), a new rhino demon transformation, new monsters, new high level weapons, an improved AI with enemies able to take cover more often; a new "Jade Master" difficulty level, with ability to import save games; a new world map interface; and keyboard and hotkey support.
