One Shot

Publishers blurb:
Welcome to One Shot: a role-playing system designed for single session gaming. One Shot is ideal for game days, pick-up games, and convention games. It is a genre-less system that a GM can easily manipulate, creating action-packed and fun adventures. One Shot is written based upon play experience in many different oneshot games in many different gaming systems. In the parameters of short, fun adventure, rules designed for longer play often hamper the quick place and rapidly-developing plots of a one-shot. One Shot tries to find "the game behind the games" and bring it to the forefront, making GMing and playing one-shots more enjoyable.

One Shot contains all the rules needed for play as well as a sample pulp/spy scenario.
