Game has been added to voting tally. If you know anybody else that's playing you might wish to ask them to add their votes here as well.
The Alpha 10 patch added offline support.
I haven't personally tested if it works "unplugged" but several forum post at the time said it did and the request for a mode that doesn't require an internet connection have stopped so I'm assuming it does.
Thanks Criel. PWiz has added the game back to the Request list.
Look up. It was just added back to the Request List. 😉
