The Mission Editor is a graphical mission editor which allows you to build, modify and debug your missions interactively. The Object Placement Tool (OPT), provided with the simulator, only shows you lists and has no debugging or error-checking capabilities.

MAG are a charity based in the UK who work to make abandoned minefields and other discarded munitions safe, so that local people can resume their lives. I have supported them for some time and have decided to give a part of each sale of the Mission Editor to them.

Up to a point, yes. If you are giving your work away for free or for a small sum (i.e. USD $10 or less) then you can use the public version of the editor to do this. If you are selling your missions for a greater amount than $10, you must contact the publisher at www.fsaddon.com to request a commercial use license.
