1. If sounds seem too quiet - hold down the "M" key to increase the volume.
2. If you need to strafe/pan the camera rather than pivot it - hold shift whilst moving the mouse.
3. In "Solo" play, selecting "Montebello" for all three of "The map room", "Le Grande Armee" and "The Coalition" gives you a really big battle with Napoleon in it.
4. If you get a CTD whenever the battle starts, persevere. I have found it suddenly works after 10 or 12 attempts for no apparent reason.
5. Turn on "Antialiasing Mode - Override the Application", "Antialiasing x4" and "Anastropic Filtering x8" in your graphics card control panel for some really crisp looking graphics.
