The latest issue of computer games magazine had quite a long preview of huxley in it.
I'll try and get some scans, but for now the main point that stuck in my head was concerning the 360 version.
It is set at a different time to the PC version a couple of years after i think. And although the players might be able to visit the same towns they wont fight each other.
It will also release 6 months after the PC game.
