From the back cover:
One Shot is a two-player game of sacrifice and vengeance.
One Player portrays The Shooter: You have been wronged... Driven to the ends of yourself and left with only one goal: to get even. Permanently.
The other player embodies The Forces: You enable the Shooter, making sure that the shot can be taken... for a price.
Vengeance isn't clean. To be able to take ths shot, sacrifices must be made. Family, friends, those who would deter the Shooter, make them turn away.
But the chance is yours. Vengeful redemption gleaming like a single bullet in the stark lamplight.
So what are you waiting for?
You've got one shot. Take it.
