Trapped in Raven's Nest

You slowly go to the bus door, where one of the thugs waits with a crowbar. He pries the door open and you step out to meet your challenge.

The head thug calls out a member called Norbert. That isn't a very threatening name.

Moments later a massive thug steps through his comrades. He must be at least 6'9'' and carries many scares from combat on his heavily muscled body.

You are completely surrounded by thugs, so there is no getting out of this fight. So how are you going to win?
