Spoilers for the 1st game:

So if Ruvik got out, then who controls the nightmare world? Does it run on auto and is everything even more chaotic w/out him?

My guess is it's a battle for control over the world with the minds stuck inside now that Ruvik is free.

tseutsumi: Ooh that's a really good guess

That's what I hope. I mean, some piece of Ruvik must be back left behind since Laura is still inside from what gameplay they also showed at E3 during their conference.

I did not know Laura was back. I bet you we will see some apparition of Ruvik in there, as well as the real world. XD
