+== Mission Maps ==
+
+Missions may use preset maps that aren't located in the *Data/Maps* directory.
+
+A mission may contain in the same directory with mission's lua script a .hwp file.
+
+This file is a zip file with an altered extension from *.zip* to *.hwp* and it contains the directory *Maps/some_name*.
+
+In the *some_name* directory the files map.cfg, map.png and mask.png are located. See the Basic Files section for more on these files.
+
+The name of the *.hwp* file should be the same with the mission script.
+
+In the mission script's onGameInit(), map should be set to *some_name*. See [LuaAPI] for more about onGameInit().
