End Game event in Kismet?

I am currently using UDK 4, i know it’s not the engine. I am currently doing a school project and am making a enemy waves style game. I cannot figure out how to end my game after the players death in kismet, can anyone help me out here?

Kismet? There no Kismet in UE4 (or rether it evolved in to Blueprint). Also UDK is just a name of a free distribution of UE3 which didnt give access to C++ tools.

So what UE do you using? UE3 (UDK) or UE4? UDK has nothing to do with UE4
