Not 'big' like 'full of features'; but 'big' like 'important and meaningful.'
Note: I want to warn/inform you guys that our Test env is going to be more volatile from now on. We've moved all the events off Test to free it up to be exclusively for testing, which means you guys get newer stuff quicker. Which means it has more bugs, but that's what it's for, right? We'll be pushing stuff up as needed to get feedback quicker.
The Test deployment later tonight is go to have the PS4 integrated into it. At this point, that means you'll see some weird UI and input bugs, along with some other weird stuff potentially. Keep reporting whatever you see as you guys normally do, we'll sift through things.
Oh, and some incentive to go check this out: There's a certain new vehicle in the terminals...
