With the increase in interest in NetEpic I thought I would repost the link to the most recent rules and army books to stop any confusion.
All of these can be found on the NetEpic page here .
The main rulebook is at the top of the page with the army books underneath it.
Anything after the heading NetEpic 5 are old versions of the rules and should not be used.
A word of warning, these are big files as they have lots of pictures and art so may take a little time to download. Also if your downloads don't look like a professionally produced document (i.e. word with no/minimal pictures) then you might be using a previous version of that document and your rules may be different (probably version 5 of the rules/army books).
Hope that helps (assuming the links work )
