Shadowrun is a fantastically lethal game, where one false move can lead to a world of pain for a player that has not yet learned the importance of common sense in the shadows. So I was thinking it'd be really helpful, for old GMs and newbies looking to run a game alike, to construct a list of things that they can use to really put the fear into their players, and make them actually think before they act.
To start us off, I can't help but go straight to the Sympathetic Detonation rules in Arsenal, which cover a set of guidelines for having a set of explosives triggered by an unrelated explosion, resulting in a chain reaction of DV bonuses and chunky salsa. Got a trigger happy street sam walking around with a bandoleer of high explosives strapped to his chest? Well put one well placed shot with an Explosive round, or toss a grenade anywhere in his general direction, and laugh maniacally as he paints the walls with his gooey innards.
