SHDN still exists. I just got it a few days ago. You can find a link on the MM site. There is a checkbox in MM to execute SHDN but it isn't enabled unless you first run SHDN. Then you can click it and pass SHDN a parameter. I haven't tried it yet to see if it actually does shutdown! Maybe just set the heat limit real low and run a game...
