I'm kicking around the idea of buying the PDF.  The description of how to handle combat related skills seems very inconsistent to me in the MHI book.  For example, "+1 HTH" and "+1 with Firearms" are not explained anywhere in the MHI book but are listed in the sample characters.  I'm not seeing that any specific weapon related skills are listed at all.  That being said, I've not familiar with the Hero system and haven't played it.  My experience is the old original D&D, AD&D, Top Secret, Traveler, and several other older games from the 70's to the early 90's.

I want to make sure that I get the correct book.  What is the link to 6th Edition: Volume 1?

I need a crash course in combat skills as they relate to character generation.  The rule book seems fuzzy to me.  Also, can anyone point to any other resources on the subject.

For example, I see "+1 HTH" or "+1 with Firearms" in sample character sheets but no description of a HTH or Firearms skill in the rule set.
