Multiplayer mode will not work in this version because a new version has already been released and the server only runs with that new version (a server for older versions is not maintained).
Instructions:
| Cursor left/right (Arrow-Keys) |
Turns cycle left or right |
| 1, 2, 3 (not on the numpad!) |
Various camera views |
| q, e |
Look left / right |
There's also two versions available, that directly run under Windows or Mac OS X. You can download these for testing from here:
