Marathon Map Editors
Mia - My personal favorite. Less features than Pfhorte, but the maps it creates have been proven to be very stable. Comes with tutorial.

Marathon Map Editor (MME) - Very user friendly and easy, although lacks all the features of other Map editors.

Pfhorte - A favorite among expert map makers. Has the most features of all the map editors available, however maps made by the PPC version of the application cannot be used on a 68K Mac. Some versions of Pfhorte have been known to create otherwise-safe maps that will crash.

Object Placement Editor (OPE) - A simple way to change the object placements in Network maps.

Marathon Edit Project - A simple map editor with the idea in mind that someone will improve it. Source code included. Not recommended for use
