Rock Band 4 was a good game, but sales were tepid. So much so that publisher Mad Catz' quarterly earning report in February began with the layoff of 37% of its workforce and the resignations of several key executives. The yearly financials for the company are now out, and the numbers still aren't pretty.

For fiscal year 2015, Mad Catz showing a profit of $4.7 million. However, this fiscal year ended with an $11.6 million loss. This despite that fact that earnings were supposedly up 55 percent. Mad Catz CEO Karen McGinnis said the company incurred about $6.8 million in charges in the final quarter because it had to write down and discount so many copies of the game with retailers.

Rock Band 4 developer Harmonix ended its co-publishing deal with Mad Catz to team up with PDP, but Mad Catz still retains about $8.3 million in RB4 inventory, which needs to be sold before September 16 of this year. McGinnis said the end of the deal was good for Mad Catz because Harmonix's future plans would have require the company to "invest additional development resources and tooling to design new hardware."  

McGinnis added that  has other things in the works to try to rebound from the poor musical arrangement. "Although the overall Rock Band 4 program was incredibly disappointing for us, exiting the relationship with Harmonix at this time allows us to focus our efforts on the development and execution of our other exciting and profitable product launches."

In the meantime, Harmonix continues to pump out DLC for Rock Band 4 on Xbox One and PS4, but it recently failed to crowdfund a PC version of the game.
