Marsquake and it's associated editor, MQEd are Shareware. You may download them free of charge, but if you intend to keep a copy I would like to ask you to send me the registration fee of £5 (five english pounds). Further details can be found in the game and editor help files. Please read these before playing.

Ok, don't worry about the £5 shareware fee any more. Since I moved, it would be difficult to do anything with £5 other than pin it to the wall. I moved a long way away.
