Jet: Who knows, He's always been one for being over dramatic..
He shrugs.
After the group make their way inside, they would see bridges and random stairways. Some that don't lead to anywhere and while others lead to doorways, below is more waterfalls of the boiling water, and all around them they can see robots being built behind glass, with robotic arms attaching, detaching and making different combinations of the spiderbots they fought earlier as well as ones that looked like their fallen ally, Blade-Wolf.
From the looks of things, everyone would have to make there way up the stairs, across bridges to avoid the boiling water below them as well as time crossing certain paths and doorways to avoid being splashed by hot water and steam as this is clearly less like a cohesive structure and more like a rats maze.
They'd find some doors locked and some being wide open to lead through more hallways where they'd see more of the machines they saw in the first city being constructed and some being new designs made to obviously be used outside of the cities, such as vehicle based looking machines with guns, rockets and harpoons. As well as seeing more of the hot water being pumped throughout the visible looking pipes of the interior of the factory.
