It's been brought to our attention that there is a bug present in the M6 Milestone that makes the game unplayable at a certain point in the plot. We have posted a patch for this here:

Just copy this file into your Resources folder of the U6 installation. You will not have to restart your game.

If you have not encountered this problem, then you don't need the patch. I can't tell you what the problem IS because that would be a spoiler. :) Sorry!
