Microsoft on Thursday filed a response to a Federal Trade Commission lawsuit aiming to block its $68.7 billion purchase of Activision Blizzard, arguing that it won’t hurt competition in the video game industry.

The FTC said earlier this month in its lawsuit challenging the acquisition that the software giant will «harm competition» among game console makers including Sony and Nintendo. Microsoft countered in its filing that the acquisition is about helping its Xbox unit to become more competitive.

«Xbox wants to grow its presence in mobile gaming, and three quarters of Activision’s gamers and more than a third of its revenues come from mobile offerings,» Microsoft said in its 37-page response. «Xbox also believes it is good business to make Activision’s limited portfolio of popular games more accessible to consumers, by putting them on more platforms and making them more affordable.»

The deal, announced earlier this year,is the largest ever for the software maker and also within the videogame industry. Microsoft, which also makes the Xbox video game console,has been speaking with regulators around the world in an effort to gainapproval for its acquisition. Microsoft earlier said it expects tocomplete the deal sometime around the summer of 2023.

The FTC’s move against Microsoft marks one of the US government’s biggest efforts to take on the tech industry, which has witnessed companies like Microsoft, Apple, Amazon, Alphabet and Meta becoming some of the most highly valued companies on the planet. Amid all that growth, competitors and regulators have been asking whether the tech industry has too much power and whether companies have been acting as monopolies.

The agency argued in its Dec. 8 lawsuit against the software giant’s acquisition of the Call of Duty maker, saying Microsofthad used earlier acquisitions to make several high-profile upcoming titles like the space exploration game Starfield and the vampire shooting game Redfall exclusive to devices powered by its software. Microsoft said it offered Sony the right to sell the military shooter as part of its PlayStation Plus service, but»Sony refuses to deal,» Microsoft said in its filing.

«The acquisition of a single game by the third-place consolemanufacturer cannot upend a highly competitive industry,» Microsoft saidin its response. «That is particularly so when the manufacturer hasmade clear it will not withhold the game. The fact that Xbox’s dominantcompetitor has thus far refused to accept Xbox’s proposal does notjustify blocking a transaction that will benefit consumers.»

Microsoft said it hopes an amicable resolution can be found that benefits all in the industry.

«Even with confidence in our case, we remain committed to creativesolutions with regulators that will protect competition, consumers, andworkers in the tech sector,» Brad Smith, Microsoft’s president and vicechair, said in a statement.

Activision CEO Bobby Kotick also defended the deal in a separate statement Thursday, saying that»There is no sensible, legitimate reason for our transaction to beprevented from closing.»

The FTC didn’t immediately respond to a request for comment.
