From publisher blurb:
Haven’t finished reading Knock! issue one? Well hurry up, the second volume is about to be sent to the printer. And it's even more full of gonzo goodness than the first one!
We did it again: we gathered some of the most respected, most creative, and possibly weirdest minds of the old school roleplaying scene and compiled some of their best work to make this thick magazine.
Once again, we made KNOCK! the overstuffed bric-à-brac we had dreamed of. We hope you still have some room on the part of your gaming shelf that's easy to reach from the gaming table!
This second issue is 224 pages It is filled with that old-school-slash-adventure-gaming unique flavour: thoughts about system and substance, useful rules and procedures, random tables and lists, pages of maps, six new classes, nine new monsters, and four complete adventures.
