As Batman you have a variety of moves and gadgets at your disposal. Much like Splinter Cell's Sam Fisher, you can skulk quietly, which allows you to sneak up behind unsuspecting enemies and dispatch them with special stealth knockouts. These aren't stealth "kills," however, because there's no blood in this game, and no one ever dies. You also have the benefit of a radar screen in the bottom left corner, which shows you the location of your objectives and the position of all nearby enemies (even the ones you can't see). From time to time you'll also see a picture-in-picture screen pop up, which can show you nearby conversations between enemies or a security-camera view. Unfortunately, the picture-in-picture screen causes horrible slowdown in the PS2 version of the game; the GameCube and Xbox versions don't seem to suffer this problem.
