It looks like those little green hamlets have been filling their noggins with all sorts of engineering tidbits. Armed with nothing more than a few spare parts and ingenuity, these Bad Piggies are set to take off and conquer Android, iOS, PC and Mac come September 27. Rovio has teased us once or twice already, but this is the first time we get to see the actual gameplay of this upcoming Angry Birds spin-off.

It’s time to see what it’s like to live in the shoes cloven hooves of the egg stealing piggies responsible for making birds quite angry. Millions of adorable green swine have been mercilessly slaughtered for simply trying to feed their families. They’ve tried protecting themselves with hardhats, makeshift houses, and have even gone as far as to leave their gravity loving homes in favor of the cold darkness of space. No matter what they do or where they go, there always seems to be a giant slingshot waiting to blast an Angry Bird at their hide. That all ends this month, with the release of Bad Piggies for Android and iOS.

The “bad piggies” have something diabolical planned, and whatever it is, it’s PIG, erm… BIG! They’ve started their social networking campaign and even “Haz a Facebook.” Now we’ve got a teaser video of what appears to be an incoming spin-off to the Angry Birds phenomenon. Perhaps it’s time for the pigs to finally have their day. We’re just going to have to wait and see, for now, here’s the teaser video.
