One of my favorite games I never played is True20 by Green Ronin. Recently I learned about two awesome new settings for that game: “Interface-Zero” and “Shadows of Cthulhu“. The first is a modern cyberpunk setting, the latter is another take at H.P. Lovecraft’s Cthulhu mythos.
Both settings are currently available at a discount price at RPGNow. For just $4 you can get two complete campaign settings for use with the True20 system.
I have no idea how long those PDFs will be available at the reduced price, so if you are interested in either game, you should have a look. As far as I know you need the True20 Revised Edition book or the original True20 book and the Companion to play the game. If you are interested in learning more about those games you should also listen to the Atomic Array episodes 05 and 10, because they feature interviews with the creators of Interface-Zero and SoC respectively.
UPDATE: It seems the special sale has ended and Interface-Zero and SoC are now available at $4.95 each.
