Continuing in a Cthulhu theme, Apathy: the Calling is a free downloadable RPG from 1km1kt (1,000 monkeys, 1,000 typewriters), a site that hosts over 400 free RPGs.

In this game you play regular folk dealing with the mythos in the only way they can in the modern age, with apathy. As one of the select few for unknown reasons you can hear Dread Cthulhu as he dreams, calling you to commit unspeakable acts. Fortunately you’ve long been accustomed to ignoring inconvenient realities. You fight back with the inertia and apathy, that has defined you as a generation of slackers, miscreants, good for nothings, baby busters and losers.
