Jared Gerritzen, lead designer on Zombie Studios' upcoming free-to-play shooter Blacklight: Retribution, has called Activision a bunch of jerks for introducing premium service Call of Duty Elite.
"I don't agree with it," Gerritzen told Gamasutra.
"Right now, if they could, they'd charge 60 bucks, then 20 bucks a month for a map pack - or even just one map - and then $9 to upload game movies to YouTube.
"They see this massive fan base, and why aren't they spending that money and evolving the game even more?"
Although he admits the Call of Duty series is "amazing", Gerritzen said Activision hadn't done anything new with the games for at least four iterations.
"That's the sad part. Think about if they tried to spend that money that they're trying to milk from the fans," he said.
"It's sad. It's really weird. But there's always going to be that guy; there's always going to be the jerk."
Activision recently detailed Call of Duty Elite's feature set.
