Alien Nature Rampage

Alien Nature Rampage is set in an alternative timeline diverted in the 1960´s. Humans  have almost consumed all life and covert all earth in concrete slabs. Now  it is up to you as an alien who takes the form of an element from nature to save humanity by destroying all the factories preferably without killing all humans. 

Current technical challenges are the need for progress to be monitored on the globe I in all scene. All advice is well received.
