Are any of the Netmech or Mercnet versions available for free download?
Yes, the standalone versions of DOS Netmech and the Titanium versions of Netmech and Mercnet are available for download from Activision. I’m not sure about the DOS version, but the standalone Titanium versions cannot be used to host games [only to join] or you will get a “cannot find CD” error. Also, because these are standalone versions, you do not have Mechlab to customize your mechs, but you can get custom versions from someone else and drop them into the MEK folder. The DOS Netmech download is ~10mb, Titanium Mercnet is ~30mb and Titanium Netmech is ~ 50mb. Seeing as these games can be picked up for a few dollars, it would probably be easiest just to buy the damn thing.
