LONDON (AP) — Microsoft has agreed to make the hit video game Call of Duty available on Nintendo for 10 years should its $69 billion purchase of game maker Activision Blizzard go through. The announcement Wednesday is an apparent attempt to fend off objections from rival Sony. The blockbuster merger is facing close scrutiny from global regulators. Microsoft, maker of the Xbox game console, faces resistance from Sony, which makes the competing PlayStation console. Sony has raised concerns with antitrust watchdogs about losing access to what it describes as a “must-have” game title. Microsoft President Brad Smith tweeted his thanks to Nintendo, which makes the Switch game console. He said the same deal was also available for Sony.
