The wacky physics puzzle game Rabbids Big Bang is going free for a limited time in the Windows Phone Store. Rabbids Big Bang takes the absolutely insane creatures from the Rayman series and launches them into space. Take a swing at your fuzzy friend at just the right angle to send them into orbit around neighboring planets. Strategically time your jetpack usage to get all of the objective items, and ultimately unlock tons of bizzarre costumes and batting implements.
You can find Rabbids Big Bang here in the Windows Phone Store. Pick this one up soon, as it's only free until the end of the month.
Rabbids Big Bang is also available on Windows 8, though it'll still cost you $1.49 there.
