One of my Christmas presents was the new second edition of The Esoterrorists by Robin D. Laws.
I'd already got the 1st edition (reviewed here), which I got after having a look at Trail of Cthulhu.
The second edition polishes the rules up a little, now that Gumshoe has been used to power a subsequent seven games (including the forthcoming TimeWatch and Gaean Reach), adds more detail to the Ordo Veritis and Esoterrorist organisations, has an expanded bestiary and includes an alternate setting - Station Duty.
It's still very affordable, and great for quick play at short notice.
Which brings me to the official point of this post - Recently a member of the Pelgrane Press Google+ community put out a call for some ready to play PCs for an Esoterrorists 2e game.
I, not having too much work that I wanted to avoid doing, knocked some up.
If you would like to use them, then they're here:
