1.0 has been out for months now, but that does not mean work on A Clash of King has not continued as usual.
While 1.1 will not be quite as big an update as 1.0, it will still be include a lot of new features. Below is a quick list of some of the new stuff included in 1.1.
Five new companions, amongst them Alysane Mormont and Sandor Clegane.
Five new quests.
Various lore characters, such as Tyrion, Sansa, Illyrio and Arya.
The Essosi troops completely re-done.
More than 100 new NPC's for you to interact with, all of them with custom dialogue. Some might yield renown, honor or items if you pay them the right compliment, but might also decrease the very same stats if you insult them. Choose your words carefully.
The ability to travel to, and explore, Yunkai and Meereen.
A lot of minor bugfixes and tweaks.
There's a lot more included in 1.1, but I see no reason to reveal it all at this moment.
While a lot of people have been clamoring for Daenerys and her army as a separate faction, I'm afraid it's just not possible. There's no way to implement dragons, and it's impossible to extend the map all the way past Valyria, the game would crash. So no Daenerys faction, though you'll still be able to visit her, talk to her, and receive a pretty cool quest from her.
So that's the gist of 1.1, it should be out fairly soon.
Don't forget to vote for A Clash of Kings for the Mod of the Year awards.
