Zombiepox is an evolution of Pox: Save the People, which was developed by Tiltfactor in coordination with the Mascoma Valley Health Initiative to stop the spread of misinformation concerning the effects of vaccination.
[1][2] Zombiepox is also designed to be educational and initial research showed that people's sentiments on vaccinations became more positive when faced with the fictitious disease in the game.
[3] Playing the game also appears to improve people's systems thinking abilities.
Players win the game if the disease can no longer spread and lose if too many people become full-blown zombies.
[5] The game won a Major Fun Award for Cooperation Thinking in 2012.
