7 Days a Skeptic takes place 400 years after 5 Days a Stranger.

You play as Dr. Jonathan Somerset, a psychiatrist on a spaceship. One day, a strange artifact is found floating outside the ship's doors. When the crew brings it in, it appears to be a coffin with the remains of John DeFoe, which somehow floated out into deep space. At first the crew believes it's nothing, and leaves it lying around. But during the night, the ship's captain goes missing. And even stranger, the box is open, and nothing is inside.

7 Days contains fewer puzzles and more action elements than its predecessor, and is also made with the AGS engine.
