The porky content update to Bad Piggies that was teased by Rovio a month ago has finally arrived.

Start your crazy contraptions‘ engines (if any), because Bad Piggies’ Road Hogs content update is here.

But wait, it appears that this is also Bad Piggies’ surprise Flight in the Night content update:

In this massive update to IGN’s 2012 game of the year, the Bad Piggies are on the move, and they’ve managed to hang on to the eggs so far! But watch out – you need to sneak past the napping Angry Birds, and they’re sleeping with one eye open! Navigate through 30 new Flight in the Night Levels but don’t make too much noise, or you’ll wake up some seriously furious birds! Also make sure to check out the new “Road Hogs” time trials: can you beat the clock (and your friends) with your crazy contraption?

And with that, Bad Piggies has gained six new Road Hogs levels and 30 new Flight in the Night levels. The Road Hogs levels, in particular, come with their own global leaderboards.

Also included in the update are six new achievements and a brand new sandbox.

The newly updated Bad Piggies for iPhone and Bad Piggies HD for iPad are available in the App Store for $0.99 each.

The Bad Piggies Best Egg Recipes interactive cookbook for iPad is also available for $2.99.

Can you race against time and be a bona fide road hog in Bad Piggies?
