Ok, then. As far as I remember Murtaugh betrayed us at the end of Sub6. Now, here lies the question: do we follow him into the rabbit hole? Yes, yes we do. As we end up in the Core, the epicenter of the Submachine structure (or network as some people call it) – we’re discovering completely new world within. Things you have never seen before in submachines, story unfolding before your very eyes and locations you didn’t think were even possible to construct in our physics bound 3-dimentional world. Mindblowage ensues.
