Savage worlds for sure. Perhaps with 50 Fathoms or Pirates of the Spanish Main settings or perhaps even Solomon Kane(not likely, but depends) for some extra fluff and crunch
Thanks for all of the suggestions everyone! I've given the GM the link to this thread, so hopefully he'll take a look at what you all recommend.
I don't know if it changes anyone's recommendations but in talking to the GM yesterday he was hoping the game focus would not be on group combat but rather quick focused strikes, then fading into the shadows. And each player would have a specific specialty (poison, the brains, knife throwing, etc.) that would give them the spotlight depending on the type of assassination that was being done.
