I'm playing a quest mod in Fallout 4 called Fusion City Rising.

The authors did an amazing amount of work and even got some original voice acting in there.  There is a new vault full of Child of Atom enemies, an underground city, and a 14 story night club. It also adds three new companions.

The "invasion simulation" pods are a lot of fun.  You sit in one of them and the city FLOODS with enemies--but since it's a simulation, you don't have to worry about all the NPCs getting killed.

The work they put in is staggering.

I bought Tokyo Mirage Sessions recently and I'm loving it, is fantastic, but I haven't been able to play it in days because a friend from London is on visit :S

First world problems.

This is WiiU, right?  This is the reason why I need a WiiU.

It kinda looks like before the apocalypse...

Well, the explaination is that it was/is an underground resort/city for the rich that's run and controlled by a powerful security firm.  It's not trying very hard to be realistic but, then again, the Institute was much the same way.  Seems to be modeled on Las Vegas.

Also, NOT for the weak of GPUs.

Well, I "gamed" my wife both Friday AND last night.  But enough with the digression.  :)

Iplayed with myself. 

but isnt it available on the XB1 as well?

Is it?  That would surprise me greatly.  Not only is it dependent on a lot of other mods but it's also 800MB and it leans on volume combat.  I bet there were at least two dozen enemies at once during the invasion.  It is pretty adult and the author even highly recommends Bodyslide and body replacers, though that can be sidestepped in various ways for a console release.
