As Syn3h draws nearer to reality, I am fine tuning the last versions of Mars Explorer.
2.22 includes the most rock solid networking ever (which is far from perfect due to fundamental flaws in Unity which they have now acknowledged), many bugfixes and refinements, better buggy and hovercraft handling, an installer for the native windows app, and much more.
If you are experiencing any issues with the browser or dashboard versions of Mars Explorer, please try downloading a native Mac or Windows app. There are some known issues with Unity's webplayer that I am working with them on at the moment.
My next milestone will be the release of the Whirld 3 library - which will revolutionize world design. After that, a complete rewrite of the networking system is in order - which is a project of such magnitude that I want to ensure that we have Mars Explorer finely tuned in it's corrent state before embarking on this new venture.
