"Phantom Liberty", the Polish company's first major new game in nearly three years, was released on Sept. 26 and had sold over 4.3 million copies within two months.

The company reported a net profit of 202.9 million zlotys ($51.54 million) for the third quarter, beating the 162 million zlotys expected by analysts and up 105% from a year earlier. Revenue for the period rose 80% year on year to 442.7 million zlotys, it said.

"We are very pleased with the launch of Phantom Liberty. Successful release of the expansion, along with Update 2.0 which introduces a slew of additional improvements, elevates Night City gameplay to another level - in terms of quality," CEO Adam Kicinski said in the earnings statement.

"This is an important achievement given our plans to further develop the franchise," he added.
