This is a model import plugin for F.E.A.R. Created by Monolith.
Created by Monolith this plugin was made for 3dsmax 7 and was suspiciously not included in FEAR's sdk. It replaces the original plugin Monolith did release for world meshes as this plugin does that as well. It does import/export.
Note unfortunately I've been unable to get this plugin to work as it crashes 3dsmax 7 when I try installing it. So I can't answer questions as to how it works. Hopefully you'll have better luck than I did.
