From the introduction to the game:
The setting in Arbitrary is modern; pretty much everyday stuff. There's no vampires, werewolves, magic,
time-travellers or laspistols. There might be psychics, but only on the end of phone lines and in labratories
in Russia. Crime is a part of soceity, much as it is in real life - there are certain areas you don't go after dark
(or even during the day). The police will beat the crap out of you if you get on their wrong side, or at least
treat you in a rather unpleasant manner. In short, there's absolutely nothing special to it - it's typical actionmovie
fodder, as seen in Die Hard or Lock, Stock and Two Smoking Barrels.
