Since we're comparing RPG stories I thought I'd weigh in. I'm afraid it's Warhammer 40k Rogue Trader rather than Shadowrun, but there's still some good stuff here.
Now, I was GMing two seperate groups at the same time here. Both groups were charging around the Kronos Expanse and attempting to dick each other over. However, one group took dickery to an art form. Some of their highlights can be found below:
- Taking over a drug cartel on Footfall by getting the leader hooked on a custom-made drug with lethal withdrawal symptoms. And then dropping that little bombshell to him over a fine dinner on their flagship.
- They took over another drug cartel with a similar method, except it involved bankrolling the leader's cybernetic upgrades, and sneaking some cranial bombs in as well.
- They routinely disposed of the bodies of their murder victims by feeding them to their Kroot bodyguards. They also used being eaten by Kroot as a method of ensuring that antagonists did not return.
Now that's just the minor stuff.
- They unleashed a WMD nerve gas on the governor's palace of a particular world in an attempt to kill the other group.
- They later attempted to create a genestealer cult on the aforementioned world in order to summon a Tyranid hive fleet to erase evidence of their prior crimes. This one deserves special mention, as there was a particular moment where they decided that punching out hobos in the middle of a thunderstorm, whilst covered in shit, was the logical course of action. (In fairness it really was.)
-They teleported into the other group's ancestral mansion, dropped a briefcase nuke and then teleported out. Oh and they stole the other group's dog for good measure.
- They purchased 400 identical sex slaves, all of whom looked like a member of the other group's favourite anime girl, just to piss him off. (Mikoto Mikasa if you're wondering) They then suffered a unexpected, and frankly terrifying outbreak of decency and responsibility. This resulted in them purchasing a starship and converting it into a mobile Victorian finishing school for the girls. They also kidnapped a therapist to treat the girls after their experience of slavery.
They are currently eyeing up godhood, and worryingly have come up with a pretty decent plan for it. It involves Orks, a genetically engineered plague, several warp drives and a supernova.
