Ubisoft has begun a $1 million legal battle with pop group Black Eyed Peas over an iOS title’s development.

The games giant has created an iOS edition of The Black Eyed Peas Experience, previously released on Wii and Xbox 360 last year and is waiting for approval from the group to enable in order to go forward with the release.

The game has cost Ubisoft $233,000 before it was left on the proverbial shelf by Black Eyed Peas all the way back in March.

"Since March 2012, and despite Ubisoft's repeated requests, BEP Music has breached the contract by failing and refusing to either approve or disapprove the IOS game in writing or otherwise," legal documents seen by Courthouse News (via Games Industry) state.

"Ubisoft has performed all of the obligations required of it under the contract, except as those obligations that have been excused by BEP Music's conduct or by operation of law."

Ubisoft claims it’s lost out on $1 million due to the actions (or lack thereof) of Black Eyed Peas. This is taking both development costs and predicted profits.
