While I was gone on vacation someone contacted Dennis Detwiller and gave him all the money he wanted to release Insylum, a Hastur Mythos rpg. Detwiller: "This fantastic individual (who I wish I could name!) has made it possible for a whole slew of half finished work to reach the world. They've single-handedly revived my faith in the game industry!"
Expect the full version of Insylum to be available for free download in the next couple weeks. In the meantime a pre-release of the game mechanics section can be found here. You can follow the development of Insylum and other Detwiller efforts at his blog. Detwiller, posting on RPGnet: "Next in the pipe will probably be Delta Green: Black Cod Island or Part 1 of Delta Green: Future/Perfect."
