The Esoterrorists

"The Esoterrorists" is a table-top RPG by Robin Laws. The
Esoterrorists are an international conspiracy to breach the walls
between the natural and supernatural, releasing horrors into our
world. The players are part of Ordo Veritatis, a secret society
fighting the Esoterrorists, because transdimensional horrors are a bad
thing, apparently.

I've never played the game, but I really like the cover art:

There's a (really) big picture behind the medium-sized one on that
page.

Is there something in the water that's making stuff like this pop up
all over? The old "Delta Green" is in this genre, as are Stross's Bob
novels and most recently "The Edge of Reason."
