1. Follow Alyx into the base and receive a rare word of praise from Dr. Magnusson. This entire level is one long scripted sequence.
2. Your only task is to press this red button and begin the countdown for the rocket launch.
4. Listen to Dr. Vance -- he is quite passionate that the Borealis must be destroyed. He is also very anxious to have Judith Mossmon safely returned. These are likely elements to be explored in Episode Three.
5. Step outside and watch as the portal is destroyed. The rocket launch has been a success!
6. Enter the hangar and come under attack from a pair of advisers.
7. Dog rescues Alyx but things don't go so well for Eli. Game over.
