The Total War Blog has an update about an upcoming patch for Empire: Total War to update Creative Assembly's RTS sequel to version 1.4. They offer a preliminary change list for the new version, though there's no outlook on when the patch will become available. According to the introduction, AI improvements are the main goal of version 1.4, saying: "A lot of work has been put into the campaign and diplomacy AI, focusing on how it wages war, makes alliances and peace as well as use of naval invasions. Battle side improvements have been made to most areas of the AI with the focus on the siege AI which has had major changes made to it. Sieges have also had a lot of work done on them with a lot of bugs fixed, improvements made to pathfinding and how guns and troops on walls work."
