The Micro‑Infrastructure Jungle: Where the City Breathes, Sweats, and Schemes

Introduction

Cities don’t just stand tall—they breathe. They sweat. They rumble. And all that happens in the micro‑infrastructure: alleys, HVAC clusters, parking garages, bike cages. These places aren’t meant for the public eye. They’re meant for maintenance crews, delivery drivers, and the occasional criminal who knows how to disappear. For a GM, they’re a goldmine of tactical chaos.

Core Tactical Features

• Ambush Geometry — Blind corners, dumpsters, stairwells—angles that make killers smile.
• Multi‑Layer Movement — Parking garages with ramps and ledges that turn every fight into a shifting arena.
• Improvised Tools — Rebar, broken signage, loose bricks—junk becomes justice.
• Visibility Control — Steam vents, shadows, parked cars—sightlines become lies.

Encounter Hooks

• A chop‑shop crew swaps stolen vehicles in a half‑lit parking garage.
• A supernatural predator stalks alleys, using steam vents like smoke bombs.
• Hackers meet near HVAC units to dodge surveillance, unaware they’re being hunted.

Summary

The micro‑infrastructure is the city’s circulatory system—messy, loud, and full of surprises. It’s perfect for ambushes, chases, and improvised mayhem. If your players think they know the city, drop them here and watch their confidence evaporate.
