"It's called the 'Water Tower Massacre,' boys and girls." Images pulsed up, filling the feed: armored prisec troopers, masked protestors, guns firing, corpses.
-from "Intervention"

Intervention is the fourth Data Pack in the Flashpoint cycle for Android: Netrunner, and its sixty cards (three copies each of twenty different cards) deposit you in the streets of New Angeles in the wake of the Twenty-Three Seconds incident. There's damage everywhere. Meat damage, brain damage, and collateral damage. We also find a new Haas-Bioroid identity, a new Shaper identity, a handful of Runner cards that dare you to run despite the risks to your health, and a place of sanctuary in which the Runners can hide.
