The special private game world for AirwaySim alliances, Alliance Challenge, was opened a few moments ago. This 3-month scenario is available to players who have previously signed up for it and have been members of AWS alliances in the past. We're offering this one-time special game world on the request of our users and as a thanks to them for being long-time members of the community. There are 7 alliances battling in this game world and also a new alliance scoring system has been introduced that allows to determine the "winner". As this is a world that required a pre-start signup other members cannot join it. However if there are members who have not joined into this game world in the first three days the alliances can recruit new members to take their places, so checking the forum in the next few days may be helpful. If you are a member who has signed up to this world please see some notes posted to our forum about this world.
