The new Delta Green role playing game is currently in development. For those who are not familiar with the game, Delta Green is a secret organization dedicated to battling the Cthulhu mythos. Think of it as the X-Files meets Call of Cthulhu. Delta Green had a kickstarter, but I could not afford to pledge at the time. One of the cool things that Arc Dream (the company producing the game) did was that they released the playtest rules of the game online.
They are awesome. I must admit that I am biased, as Call of Cthulhu is probably my personally highest rated game product. Delta Green uses the Call of Cthulhu rules with plenty of nice modern editions. It looks like all CoC 6th edition material will be easily adaptable to the new system. The additions to the system really make the game run smooth. There are rules for automatic skill checks, heavy damage for modern weapons, and sanity rules that make sense. Characters develop disorders based on the situation instead of some random chart.
The best part is that the quickstart rules have been released as a pay-what-you-want file on rpgnow.com. Go check them out.
