I've sent out the first beta version (it contains the whole pack). I'm now willing to say a bit more about the pack itself.
There are 10 levels: five Bank Robbery levels and five Jailbreak levels. They're of medium size, intended for between 6 and 16 players. I'm hoping to release some time in January, probably closer to the end of the month than to the start.

I still need some more volunteers in this thread.
