Andrew Owen posted another update concerning U3.5: Pax Britannia to the Ultima Dragons Facebook page, this time showing off a slightly adjusted version of what I gather is Castle Britannia in the game:

As well, he also made available some additional images, including the latest version of the Pax Britannia tileset and the final version of its box art (because, yes, he’ll be replacing physical boxes. You can find these at the project entry.

As well, Andrew has made a few additional town map changes, for which new screenshots haven’t been released:

I’ve also removed the ankhs from Skara Brae and Cove, but it didn’t seem worth posting updates for those. In fact the ankh is now out of the tileset, replaced by the serpent (visible above). I’ve also removed the balloon and brought back the healing booth. These will be available between towns to reduce your chances of being killed in the wilderness.

He has also finished adding text to the character generator, and has the path cards displaying properly astride the abacus graphic. A demo version of the character creation process should be available soon.

It would seem that work on Pax Britannia is progressing handily!
