The commercial PTS for the multiengine rating includes a demonstration of Vmc. The real-world demo involves just bringing an engine to idle, not actually shutting it down. Recovery is also at the first loss of control. You'll shut the engine down and run right into a Vmc stall for fun. Hey, it's a simulator, right?
You're back near Seattle, just 3,000 feet MSL. You'll want some power to do these well, so you'll leave Colorado for a bit. You're level at 3,000 feet on a heading of 330 and a speed of 101. Hold that heading, and shut down the left engine with the fuel selector. Go to full power and full-forward prop on the right engine. Use right rudder and a slight (2-3°) right bank to hold your heading.
