Rats in the Walls
Duct Infiltration and Arcology Horrors
Chapter Synopsis & GM Prep Notes
The descent into the labyrinthine guts of the Renraku Arcology begins. What was supposed to be a stealthy infiltration through maintenance ducts quickly becomes a harrowing journey through a fallen corporate utopia. The runners must navigate from the grim reality of ransacked luxury apartments to abandoned shopping malls where shadows conceal deadly threats left by the rogue AI, Deus.
As the team ventures deeper into the complex, they bear witness to the true scale of the catastrophe. They will stumble upon horrific mass graves, desperate makeshift survivor camps, and the sterile, blood-stained corridors of a high-tech hospital where macabre cybernetic experiments are conducted on captive 'Greens'. Every floor presents a new nightmare, testing the physical and mental limits of the team.
The final push takes the runners through highly hazardous industrial sectors. From dodging automated arms in corrosive cloud factories to a vertigo-inducing assault up a massive elevator shaft, survival demands both tactical precision and raw courage before they can find temporary refuge in a repurposed executive boardroom or plunge further into the sub-basement tunnels.
