Fans are invited to make animated films using the licensed Halo construction toys.

To celebrate the tenth anniversary of the video game franchise Halo, Mega Brands is offering fans a free Mega Bloks set for each stop motion animation they contribute to the competition.

The submissions are already stacking up at halotoymation.megabloks.com, where fans can also find rules, regulations and tips on how to create a stop motion video are also available at the mini site.

The winner will have their film featured on Microsoft’s official Halo web channel and prizes include video production hardware and software and limited edition Mega Bloks sets.

The contenders will be wittled down to a shortlist of ten on October 17th and Mega’s panel of expert judges will decide the winner a week later on October 24th.

Andrew Sparkes, VP of boys brand management at Mega, said: "Mega Brands and Microsoft have shared a highly successful partnership building an incredible fan base around the toy franchise over the past three years.

"This contest is such a great opportunity because it allows us to see the love for our product shine through the creativity of our fans in their productions."

Frank O’Connor, franchise development director at 343 Industries said: "Halo has always been a universe in which input and creativity from players is paramount and essential to the unique feeling of interaction and intervention the Halo sandbox encourages, and Mega Bloks is and always has been the perfect extension of that feeling into the "'real' world."
