"A team of four agents, each a specialist in one of the four elements - water, fire, air and earth - have been miniaturized to microscopic size in order to investigate a mysterious new virus that appears to be of alien origin.
The virus mutates rapidly, mimicking each of the four elements. But something went horribly wrong, and contact with the team was lost. Now the virus threatens to grow out-of-control."
This game was made in 2016 and just popped up as an AtariAge Store spotlight. Predicting the future or just a big coincidence???
