When using the npc spawn code to make an NPC appear, an extra word (or words) can be added to give the character a unique name. For example, to spawn a Stormtrooper named "Stormy", type npc spawn stormtrooper stormy in the console window. Stormy will act like a normal Stormtrooper, but is identified uniquely. Thus, using the command npc kill stormy will kill Stormy, and him alone. Another code that could be used in conjunction is control, as in control stormy, which functions like the high-level mind control. If there is more than one NPC with the same name, the control command will take control of the first one that was created, whereas the npc kill command will kill all NPCs with the same name.
