Guns don't kill people, murderhobos kill people! Specifically, when they engage ED-209 in a firefight for control of the strategically vital playground in the middle of an oil refinery, and miss.
Below is a random generation table for determining what happens when player characters in a modern or cyberpunk roleplaying-game miss what they're shooting at. The table is designed to be rolled when a character misses a shot with a projectile weapon in a dangerous area. Or a crowded one. Or rolls a critical failure. Or the GM is feeling particularly vindictive.
The collateral damage table is very much inspired by the Ship Collateral Damage table in the Rogue Stars wargame. It's much shorter, because neon slicked streets lack some of the exciting options for catastrophe a spaceship possesses - atmospheric leaks, artificial gravity failures, that result which causes the ship to burst into flames and kill anyone who can't get to an escape pod...
This table should also be rolled if the PCs leave a loaded gun with a toddler or take lots of drugs before the run or decide to go into a night club with their helmets on and their assault rifles loaded (every Cyberpunk 2020 party has done this, without cause. Every Shadowrun party has done this, as a survival necessity).
The dice rolled varies depending on local conditions.
For a region free of bystanders, roll a D10.
For a region with a few non-combatants nearby, roll a D12.
For a crowded room, a crowded theatre or a crowded crowd, roll, a D20.
The GM decides exactly where in the environment the effect applies. Remember bullets frequently, like, pass through walls.
