Welcome one and all to Spyfest, the largest super spy convention in the world! You are here to get a precious piece of secret information, but there is a complication: Everyone is wearing a costume, and you don't know who your source is. Find your spy by listening and talking to the visitors, but you have to remember that the interceptors are on site, too, and they might get ahead of you and unveil your spy before you do!
Spyfest — released in Russia under the name Spycon — is a storytelling detective party game in which players split into two teams and take turns being the spy. The goal of the spy is to make their own team guess which costume they are wearing in such a way that the opposing team wouldn't get it. In order to do this, the spy and their team use a special keyword as well as their quick-wittedness, limitless fantasy, subtlety, and impressive talent for mingling.
In Spyfest, the most creative and ingenious team wins, so most importantly — stay on your toes!
