So this is something i put together myself for the wiki I'm working on. Decided to get back into trying to show you all more artsy stuff from myself again. Figured no one else will be able to express how i see this better than my own self.
Earth as it is 730 days into the Bal'Kars initial outbreak. The atmosphere undergoes drastic changes. Australia has been completely overtaken and is now beginning to reach out to other countries by the oceans, growing large tendrils networks through the ocean, however is proving difficult for them as they cannot compete with the ocean currents. The currents are still proving to be an even worse scenario however as the currents are taking biological extract and the outbreak is now beginning to spread to the rest of the continents.
Biological agent released from infested zones into Earths Co2 and H2o. State of California, Nevada & Arizona are under strict quarantine.
The total number of converted within the state are now said to be in the 10 million mark. Evacuations across the states have proven to be a huge success considering the events. With the evacuation of 50 million people, it is the largest statewide evacuation ever attempted by the USA with a 20% conversion rate thus far. Other states have also had to quarantine areas that have become infested too. Mankind is finding it hard to stop the infection as the Bal'Kar efficiently tunnel more of their hive networks underground. Not to mention the noxious spores now blanketing the planet.
Black flesh firmly has a foothold and quickly spreads as a city would, growing over and replacing everything with thick hive flesh. The hives continually secrete bio extract that is making its way into the oceans.

Please note: I initially did a google search for "Earth Wallpaper" and used one of the provided images to do this picture in a way that i can show you!
