The idea is this:
You are an assassin, you then log on to the website and recieve a "Marks" info card. this info card would contain contact info and alergies info and a picture. it is then up to you to go and kill your mark with as few witnesses as possible. this can be done using Nerf weapons, water guns, anything just use your imagination. That is why there is alergy info. this is still in major planning mode so many of the liabilities, rules and other details are being ironed out. As it stands it seems that it would be a major liability so I am trying to figure out how to make it so that everyone stays safe.
