PAN Vision and Tactile Entertainment have released Pigs in Trees, a new iOS game that puts players in charge of a group of tree-dwelling pigs that must defend their home from an invading army of woodpeckers. Described as the antithesis of Angry Birds, players use a real-time line drawing mechanic to navigate their flying pigs around a map shooting down enemy birds and racking up points. The game provides multiple ammo types and power-ups and challenges users with different types of enemies each with their own abilities as they play through three campaigns and 45 levels. Game Center integration provides support for tracking and sharing achievements and high scores. The game is available in separate versions, Pigs in Trees ($1) for the iPhone and iPod touch and Pigs in Trees HD ($2) for the iPad.
