1942 Shadowfront Tabletop Roleplaying Game

Publisher's blurb:

Shrouded in the wretched fog of war, beneath skies scarred by the crimson raking of artillery fire, there arose a horror unseen by the world—a specter of malice that moves in silence, corrupting nations as rot consumes the marrow of bone. The war—yes, the Great War, they call it—rages with an appetite insatiable, devouring the innocent and the wicked alike, yet beneath this grand and deafening masquerade of violence, there festers a shadow far more insidious.
