A Half-Life 2 mod, I installed and tested this with a Steam installation
of Half-Life 2/The Orange Box. The Orion mod itself is still in beta (I
tested 1.0), and so is subject to change/improve over time.
Currently, I found the game to install correctly and start to main menu.
You cannot start a locally hosted session (crashes at startup) and
joining an internet hosted server results in a connection issue (you get
a message saying you're already logged in from another machine - which
you're not, so don't get paranoid about your Steam account being hijacked ;
it's not that, the mod itself is not working properly yet in CXG and that
causes this error) -- I'll recheck this mod periodically as updates are
released to see if the current situation improves any.
A known not to work ranking is appropriate here me thinks....
Cheers!
