Revenge of the Giants is the first WotC “mega-adventure” for 4e. It’s also the first adventure put out by them for 4e that comes in hardback book form (with a double-sided flip map attached in the back) instead of the double book folio style. The book is 160 pages and takes characters from 12th to 17th level. This is a review based on one read-through and has not been played in any part by me. This review contains some minor spoilers as well.
