Apparently, a tool very similar to the Marathon Map Splitter. I haven't tested it extensively, but it seems to work as advertised. Not a new tool, just not here before.

Not technically Marathon sounds, but rather a MacOS 8.5 SoundSet. Pretty well done, overall... a few sounds are rough, but so were the originals.

Produces an amazing array of info about a map (or a folder full of maps), including all basic stats (polys, floor space, weapons availability, textureset, etc), and some aggregate stats on multiple level maps. It was inspired by MapInfo, but generates much more information. This update is a complete overhaul. There are statistics on new things (including textures, lights, liquids, and sounds), and special value statistics, and the source is completely Loren's (all of Kirill Levchenko's code has been replaced). Source is included.

Exports Marathon2/Infinity maps in a variety of 3D formats. Useful for porting to other games, or for making cool term art for your solo scenario. Comes with source code, so you can do with it as you see fit. You can see a couple of samples of the output, imported into Bryce: AyeMakMetal.jpg (118K) and WaterlooMarblepark.jpg (200K). Updated with new info-if you already have this file, you can download just the new documentation (227K). This update adds support for the M1 format (including correct handling of texture numbering).
