Bad Piggies alters the expected Angry Birds formula, having players construct various contraptions and guide them through rickety levels, while collecting stars and demolishing crates of TNT. Bad Piggies, it turns out, takes more cues from Rovio's Amazing Alex than from its pop culture smash hit, Enraged Poultry (title paraphrased).

Players build flying, rolling, roaming contraptions using a grid system, and then set the naughty pigs free, attempting to "three-star" each level. Check out a gameplay video showing off this set-up on Y!Games, and if you're really into pig products (bacon included) read the Bad Piggies comic here.

Bad Piggies and Angry Birds are "complete opposites," Rovio EVP of Games Petri Järvilehto says. "Angry Birds smash things up, Bad Piggies build stuff. The pigs are all about making plans and building things, even - and especially - when they don't work!"
