Delta Green: STATIC Protocol enhances the Impossible Landscapes campaign by collecting even deeper research from its sprawling timeline. Agents can piece together these fragments as they pursue secrets they may regret. Secrets of otherworldly power. Of murder and memory that lengthen like the shadows cast by sinking suns. Of an invitation to a masquerade that never ends and is the end of all things. Of the bitter truths of Carcosa, The King in Yellow, and the Yellow Sign. STATIC Protocol is a full-color sourcebook for Delta Green, the role-playing game of Lovecraftian horror and conspiracy.
