If you feel like paying Creative Assembly another ten bucks, now you can download the Warpath add-on campaign for Empire: Total War. It adds Native American factions with unique abilities battling it out on a map of America. However, if you're only inclined to pay Creative Assembly another $2.50, you can just get the bonus pack that now includes a few more tweaked units, playable in the single player campaign. For instance, the USS Constitution up there.

However, if you don't feel like paying Creative Assembly anything at all because you remember the return on your investment when you bought Empire: Total War eight months ago, you can check out the latest patch for free to see how the game is coming along. Once again, AI fixes are among the patch notes.
