In the official FoMK forums you will find some very well presented previews of missions from within the Beta2. The first is a hostage situation in Tokyo, the second is a jail break in De Morgans Castle and lastly they have the "Battle for the Dome". Each feature shows many screen shots with dialog as well as a description of the events taking place.
