Andreas J. said: What's the changes from existing "Delta Green" to this new "Fall of Delta Green"? A whole lot! It uses a different game engine entirely, an engine known as Gumshoe. So whereas Delta Green itself is a d100 based system, the new Fall of Delta Green is d6 based. Gumshoe Engine is all about empowering players and storytellers to run more cinematic games. Kind of like a procedural television show. Core Clues that move the plot forward are guaranteed, meanwhile you can "spend" points from your Investigative Abilities to get extra information or just snag the spotlight for a few minutes. Lets say you want to smhmooze your way past some guards to get into a location you aren't supposed to go to. In Delta Green proper you'd probably need to roll HUMINT or something like that. In Fall of Delta Green though you just spend a point from your Flattery Pool. A point that won't refresh until the next operation. Its all about managing your resources represented as point pools. Like Gumshoe is normally. As for the differences between this and other Gumshoe games...I'm not an expert on the systems as far as knowing the differences between all the versions of Gumshoe but one of the things that stands out as very different is the "Lethality Rating" system for combat. Weapons have a lethality rating such as L2 and if they ever roll a 2 or lower on the damage then you're instantly killed. If it rolls a 3 or higher you add 5 times the lethality rating to whatever you rolled. I'd assume quite a bit more than I mentioned changed.
