Capcom official announces Flock, though a preview (story) already revealed the existence of Proper Games' upcoming downloadable puzzle game that's due this holiday season. The game is being developed by vets of the development teams for Crackdown, Battlefield 2: Modern Combat, and Lemmings, and the later game seems to be the inspiration for this flocking game:

SAN MATEO, Calif. — Jul 15, 2008 — Capcom® Entertainment, a leading worldwide developer and publisher of video games, today announced Flock! (working title) for PLAYSTATION®Network, Xbox LIVE® Arcade for the Xbox 360® video game and entertainment system from Microsoft, and Windows® PC. Developed by Proper Games™, whose talented team members are known for their previous work on Lemmings, Crackdown, and Battlefield 2: Modern Combat, Flock! is currently scheduled for a downloadable release this Holiday season.

In Flock!, players take control of a UFO that has been given the challenge of herding farm animals to its mothership through a variety of puzzle-filled interactive levels, including corn fields, pastures and other “plushie”-like environments. In order to succeed, players will have to manage the quirkiness of the animal’s distinct behaviors, as well as solve a series of environmental puzzles using Flock’s! physics-based gameplay. The animals that populate these islands – sheep, chickens, pigs, cows and more – respond to the UFO in all kinds of eccentric ways based on their nature. By finding or creating a passable route across a level, players can herd the animals safely toward their ship. Solving the puzzles within the suggested time limit yields exciting rewards, but players can also take their time in order to find more hidden bonuses. With a unique theme, clever humor and easy pick-up-and-play controls, Flock! promises to be an instant hit with gamers of all ages!

Flock! uses a sophisticated physics engine that drives the challenging puzzle elements of the game. Whether using the Tractor Beam to move obstacles out of the way or the Depressor Beam to stamp out crop circles to guide your herds, being an extraterrestrial has never been this fun! Friends will also be able to join in on the animal herding adventures through co-op play. And when all the levels have been completed, the journey is just getting started as users will be able to make their own customized puzzle-filled levels using the level editor. Flock! comes packed with so much content, the potential fun is out of this world!
