That's I think the first footage of a "real" network game too. I believe all the previous videos where local network setups of either us playing here in the office or at some venue with 12 Xboxes networked. That's San Diego Comic Con players playing with and against players here in Washington, not all of whom were in the Uber offices. Obviously, looks exactly the same, and that's a good thing.
Best gameplay so far, because it's actual gameplay. The dev explaining things on the side is also a plus.
