Data File Upload Page
Only HeavyMetal BattleMech, Vehicle, ProtoMech and
AeroSpace Vessel data files (*.hmp, *.hmv, *.hml and *.hma files) may be uploaded.
After uploading, data files can be viewed in the appropriate
User-Submitted Designs page.
Once your design has been successfully uploaded, you will be given a link to
that file, which you can then copy to a forum post or other location, in order
to link back to your uploaded file. Of course, you can view and download any the
files using the main User-Submitted Designs
