Gunman
the sim is 90% about how you act as a crew member, 10% about flying ability. Help each other. You won't score points for not helping the other guy when he's struggling where you didn't.
Treat it as a normal flight and make normal requests to ATC for help - vectors, weather, etc. We even asked "company" where they wanted us to divert to - "company" politely told us we had to make that decision for ourselves!
Enjoy
