It's had a slightly troubled development - first getting sued by Tim Langdell over the use of the Edge name (the bastard), and now put on hold for a few months as the developers' new owner (unrelated to Langdell) sorts some things out.

But at the end of the day, it's still an awesome looking action game set in a beautifully realized Steampunk world.
