From the Publisher's Website:
The Operation: an international and independent covert ops organization dedicated to the safety of mankind... or it's subjugation. A game that explores what it means to be a secret agent and the impact that it has on your mind.
Characteristics (which are customised to a character rather than chosen from a list) have a rating that affects which die is rolled in respect to them: d4 for Futile, d6 for Average, d8 for Proficient, d10 for Expert, d12 for Master. Characters also have an Edge attribute (rated 1 to 10) that measures their mental stability and overall humanity.
Conflicts are resolved through rolling the appropriate dice (with modifiers), with the higher result winning. The greater the margin in the rolls, the more extreme the result.
Players can also spend Drama Points (awarded by the GM) to achieve cinematic effects.
