I AM NOT THE AUTHOR OF THIS SOFTWARE
I notice that the version of Marathon: Freedom on Simplici7y is actually out of date. CubicCircle released a 047 version some time after the 036 version (the one on S7 now), but it seems that isn't available here anymore.
I am uploading this for posterity.
Marathon Freedom v047 by CubicCircle.
Application is available in MacOSX only, since, well, that's the only version I have.
Improvements since 036- two new levels and a World Arena: three new tracks. Tears of K'lia architecture slightly modified.
