Clavius downloads
Clavius And Beyond 3.70 is based on 3.50 version, ported to EV Classic for Nova by Chris, with SpacePort software. It contains minor changes and fixes in order to look like the original 3.33 release best, and resources cleaning.
Clavius And Beyond should NOT be compatible with other plug-ins, so it’s highly recommended to remove any other plug-ins.
In the same way, it is strongly recommended to use a dedicated Pilot file to play plug-ins.

If first mission "Welcome to Clavius" is not available on any in-game Mission Computer, install included Clavius Cleaner plug-in, and complete the special Computer mission.
Enjoy... hit hard and good luck!
