Phil has personal experience with this situation and has offered insight on how to wake people up.
Stark is stuck in the game. We'll need as many here at the Tower
to help assist Pepper and to act from a centralized location.
If you've found anyone that's still inside the game, they need to be brought to the clinic in the tower immediately. If you need a portal, ask here.
If anyone else has any skill with hacking, or knows anything about virtual reality simulations, Stark's tech team could use the help. Right now they're trying to keep the server stable and to find a way to those who are trapped inside.
