Tanks, Tentacles and Terror! Launch yourself into an epic late Secret War adventure that takes you inside the secret offensive within the Battle of the Bulge! It is December 1944 and the Allied advances after D-Day come grinding to a halt on the borders of Fortress Germany. As the first snows fall, both sides eye each other warily across the lines, content to rest and recuperate as winter sets in. But there was one last grand gambit planned, a massive, armored offensive, which will split British and US forces and hurl the allies back, so he can recapture the deep-water port of Antwerp. Concealed within the main strike, a scientist known as the Blackbird plans to unleash his legion of monstrous panzers and terrifying new shock troops, to cut a swathe through the allied lines. But other forces are also astir beneath the boughs of this ancient woodland, as a cult of evil men seeks to revive an ancient godling and unleash madness and death. As these powerful forces contend, Section M dispatches a crack team of experienced agents to investigate. Can they thwart the occult's plans, and foil the rise of the Slumbering Horror, or will they, like so many others, succumb to the Forest of Fear? And epic late war adventure featuring both a battle against the German's occult and an ancient evil lurking beneath the forest's Boughs! 11 Awesome missions await, taking you from your first steps beneath the trees, to an ancient Elder Thing undercity, a cursed monastery, and an epic finale at the Blackbird's Nest. An array of awesome art, maps, playing aids, GM tips, and handouts bring the Forest of Fear to life! This is an Expansion and requires the Achtung! Cthulhu 2d20 core rulebooks to play.
