Hi, Charles, I think you are supposed to follow the link and undergo the 'purchase' procedure, as there is currently a special offer at $0.00 for this nice chess variant.
There is far too much in it to summarise it here in a comment. There are 6 different armies (one of them the FIDEs), and each of the new armies is equipped with 'mutators' (as George terms it) that still feel fresh and unusual.
Besides the new armies, the general rules are extended by new ways of winning the game, bringing down the number of draws, and duelling (introducing a poker-style element). So Chess 2 is different even with FIDE vs. FIDE armies.
