My new "Desert Mix" mission has been available for a couple of weeks now, but I forgot to mention it here. It takes place in the beautiful old "tunisia" terrain, and simulates a collision between a large allied striking force and an equally large axis striking force over the North African desert. It's available for the current version of Aces High and also for the classic old version 2.12.4. Here's a link with video previews, mission download files, link to the required terrain, etc:
