Multiplayer Compatibility

To play Descent 3 v1.5 multiplayer, you will need a 1.4-patched dfmc.dll file: the version from the CD will not work. You can connect to the following 1.5 servers:

96.9.208.115:2092 - Hosted by DescentMax7930, v1.5 Stable
64.44.131.41:2092 - Hosted by DescentMax7930, Piccu Engine (by InsanityBringer)

Bear in mind that v1.5 Stable is not perfect and multiplayer is largely untested as of yet. Please have fun while testing and report issues as encountered.
