The Green Man a menace to the PC's coming up.
I've just started an Amazing Adventures rpg by Jason Vey game last night. The PC's ended up crossing over into an alternative world time line of 2100. The mono skyscrapers of the preserved New York Sky line greeted them. This was after tracking down the cybernetically enhanced courier of Nazi dimensional traveler from 1952. The world of these Nazi is world where Operation Spark in 1943 succeeded in killing Hitler(or did it). Germany sued for piece in the world courts but continues hostilities with the Allies They turned over the hierarchy & infrastructure of the German high command responsible for the Final Solution
Israel was founded much earlier in this world & continues to play a part in Western affairs.
This Nazi Germany has been locked in a Cold War with the Allies since the war's 'end' & continues to operate through powered agents, individuals, & teams. Now they've been raiding alternative dimensions & time lines. They've stumbled upon the world of 2100 where the countryside has mostly been abandoned & come across a Great Race of Yith library beneath the ruins of a castle in up state New York.
What the characters also learned is the criminal mastermind known as 'the Alchemist' has been running a slave trade & human traffic ring in New York city of this alternative 1952.This bastard controls all of the major smuggling & drug traffic from the Salt Marsh neighborhood down on the water fronts. He has ties to the Nazi smuggling agents into New York. Their latest agent came in on the Sea Witch.
Yes I'm running U1 The Sinister Secret of Saltmash by Don Trumball with a Troll Lords Amazing Adventures pulp/super hero spin. So I'm dumping the whole Scooby Doo aspect of U1 & turning the Alchemist into a lich/pulp villain of incredibly evil aspect.
