From publisher blurb:
A terrorist's desire to gain redemption sends the party on a race against time to locate his former associates before they can execute a horrific plot. As the adventurers make their way through a murky world of secrets and betrayal, the stakes — and the cost of failure — have never been higher. Meanwhile, a third contingent, which has dealt itself into the proceedings, moves ahead with plans of its own to take advantage of the situation. The heroes find themselves needing to call upon all their skill and experience to put a stop to both schemes.
Past Imperfect is a short science fiction adventure using the Cepheus Engine, Cepheus Deluxe, and the Original Science Fiction Roleplaying Game rules. Other 2D6 systems are easily adapted.
