Delta Green: Observer Effect + complimentary PDF
Chaos looks back.
The Olympian Holobeam Array, funded in part by the U.S. Department of Energy, was built to delve into a fringe theory of physics. It uses highly classified technology that its parent company developed in conjunction with the U.S. military.
A few hours ago, the Holobeam Array went online. A few minutes ago, it went offline in a catastrophic power surge. Its engineers soon restored power and communications. Its lead researcher said everything was fine.
Delta Green, a secret agency dedicated to investigating, stopping, and covering-up deadly incursions of unnatural forces, had reason to suspect otherwise. It immediately pulled strings to launch an emergency inspection, sending the players’ Agents to investigate, under cover of a Department of Energy safety inspection.
The Agents have no idea what they’ll find when they reach the Array.
