For a team new to 4ed the first run Ive used was their meeting, organized by the face character, who wants to assembly the team to run with. Thez meet in the pubm, so it was a nice place to throw in some fistfights when an evening moves toward midnight, so they have a chance to experience close combat rules. They have broken some noses, so on their way home they were stalked and attacked by some gangers, whose friend got beaten in the pub..good way to show them how the surveillance and shadowing works, and introduce some firefight. They had a feeling that they know how to handle this things. Next run was magic. Not being very nice man, Ive sent them to resolve the strange hotel where guests keep disapearing. First, there were ghouls...and from this point, there was a lot of ghouls in all our games till then. Then there was a hotel...massive Shedim infestation. When paramedics evecuate them from the roof of building, burning and collapsing around opened astral gateway, they had a feeling of how magic works...those 3/5 who survived this run...next run introduces matrix...but that is another story...
