Welcome to tonight's Delta Green operation. The year is 2081, and humanity has finally managed to recover the Event Horizon, a legendary deep space research vessel that disappeared during its maiden voyage in 2047. For 34 years, the vessel was considered lost, until a routine asteroid mining operation in the Kuiper Belt discovered it drifting silently, its systems offline but hull largely intact. The Event Horizon was supposed to be mankind's first step into interstellar travel, featuring an experimental gravity drive designed to create an artificial black hole, folding space and allowing instantaneous travel between points in the universe. When it vanished during its maiden voyage, most assumed some catastrophic engineering failure. Now that it's been found, Delta Green has taken interest - particularly in the disturbing distress signal that was finally deciphered. In the garbled message, the ship's captain, Dr. William Weir, can be heard saying, "Liberate me... ex inferis." Save me... from hell. Your team of forensic specialists has been assembled to investigate the recovered vessel before it's brought back to Earth. You'll be boarding from the USSC Goliath, a military research vessel currently holding the Event Horizon in orbit around Neptune.
