Yep. You know that you don't play the mod under singleplayer, right? You play using "coop", and adjust the settings from there. If you choose singleplayer, barely any of the maps will be present.
If you are playing on singleplayer, Alam Halfa should be there. It's kind of like Tobruk in 1942, with British lines of defense defending against Germans. Both sides have an airbase.
