On a planet in this Universe the pollution has reached such high levels that it evolved with the help of a viral infection. It has became a living entity. The Entity now spreads its goo and is destroying worlds across the Universe. But not this world! Not OUR world! We are powerful and we will stop it! Tutorial: You need to own 7 forests before goo spreads too much. You can build walls near the forest or the other wall. You can build forests on unoccupied space on the board.
