Unity Technologies has announced the launch of the Unity 3.5 open beta including a developer preview for the Adobe Flash Player deployment add-on. To celebrate this, they’re launching a Flash platform game development contest where contestants can enter their Unity-based Flash titles for the chance to win the $20,000 Grand Prize.

“Our vision has always been to let developers take their games to as many places as possible — and Flash deployment greatly furthers that,” said Nicholas Francis, Chief Creative Officer at Unity Technologies. “While we normally wait to ship our software until it’s rock solid, the Flash publishing option is just so awesome that we had to do a developer preview. I can’t wait to see where our new and existing users will now take Unity.”
