You've previously heard me praise game companies who put the rules for their games up online for free. It's a great way to show that they trust their rules are good enough to have you come back for more. It also lets players test out the game before they dive headlong into it. Privateer Press has now put the rules for Warmachine and Hordes up online for free.
Along with that, they are running special deals on the Forces Of: books for both game systems (well, both halves of the same game system). The special deals are only good through September 3rd, so if you want them, you'd better hurry.
