In Kejim lvl 1, go to the place where the pipe explodes ALL THE WAY. Noclip into it and spawn a shadowtrooper on each end and spawn a luke in the middle. Then go to one end and use notarget and un-noclip. Once the rumbling starts, noclip to the other side. Then you'll get a cutscene in where the npcs die from the fire!
Of course, you can just spawn 3 shadowtroopers and see them run!
PS: You can stand on top of the probe droids with notarget. Pretty fun to spawn a couple of stormies on one and shoot it down!
