It's the first page of the Earth Wars mobile game's BW tie-in comic! The next two pages will be on TFW2005 and Seibertron some time soon, and then there's a live vote on the game's official Twitch channel for how the fourth and final page will play out. Details in the front page article.
You can also win the original art! See this thread for details.
