Changes from the Xbox version includes increased resolutions up to 1600x1200 (1920x1200 in Widescreen), new special effects and redrawn textures, two new martial styles named 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 savegames; a new world map interface; and keyboard and hotkey support.
well to answer your questions, this was a hyped up game for the xbox, but to be honest many other fps are better then this. When it was coming to the pc, some people thought it would be a descent port with at a cheap price but MS slapped us in the face, twice! First time... saying REQUIRES VISTA , second time 49.99!!!!!!!!!!!
