Halo's original composers, Marty O'Donnell and Mike Salvatori, are suing Microsoft over unpaid royalties for using their music in the upcoming Halo TV series, as reported by Eurogamer.
The composers claimed that they previously signed a contract with Microsoft that gives them 20% of profits for the use of Halo music outside of the games, which means they should receive their share of the profits for the use of the music in the TV series.
While Microsoft pays them quarterly, the composers believe that the amount they received isn't the same as what they're owed through the contract.
"If this is 20%, then it doesn't seem like Microsoft is really making much money. So we would say, 'could you guys tell us what the numbers are?' And then they just wouldn't. But sure enough, four months later, you would get another little cheque, and just, 'here's your amount'," O'Donnell told Eurogamer.
A pre-trial for the case is scheduled for 9 May.
