In this chapter, we covered the basics of a number of ways to make your level feel more complete and interesting. It's not just a box on some ground to run around in. Now it's a run-down old building or a space station or whatever it is we wanted to make. The next step is adding some gameplay. To do this, we'll be looking at Kismet, UDK's visual level scripting language, and Matinee, UDK's in-game cutscene tool. Once we're finished with that, we'll be well on our way to having a playable game.
