Gamers say they are unhappy that one of the most hyped video games of the year will cost them £10 more than most other games on the market.
The company behind Call of Duty: Modern Warfare 2, Activision, have set a price of £55 instead of the regular £45 for most other new releases.
The first Call of Duty: Modern Warfare game was the biggest seller of 2007 shifting more than seven million copies.
The latest version is released in November and will be one of the biggest sellers of the year.
Eighteen-year-old Gary from Islington in London doesn't care about the price and says he'll definitely be buying it.
"I know we'll still buy it because once we've got the game you can't stop playing it.
"£55 is a bit too much though, so a lot of people will take longer to buy it. But, me personally, I'll buy it because there's no better game than Call of Duty. I know that for a fact."
But not all gamers are so happy with the higher price. Gaming blogs and websites are getting lots of negative comments about the £55 Call of Duty will cost to buy.
Chris, who's 25 and from Bromley in Kent, says he's going to wait for a secondhand copy.
"Why should that be much more than the rest of them? I think £45 itself is tops," he said.
"Considering that CDs and DVDs have all come down in price over the years as technology's progressing, it's funny that games haven't. I'll probably still get it but I'll get it pre-owned."
Other game developers will be closely watching what happens when Call of Duty: Modern Warfare 2 is released.
If it still goes to number one and sells millions of copies, industry experts think other companies could do the same with their big releases and charge extra.
But it's unlikely that every new game will start costing more.
