Law firm Wolf Haldenstein Adler Freeman & Herz has become the latest to file a class action lawsuit against CD Projekt. The firm claims that CD Projekt made statements about the condition of Cyberpunk 2077 that were false or misleading.

Similar lawsuits were filed by Rosen Law, Schall Law and Bragar Eagel & Squire.

At the same time, Poland’s Office of Competition and Consumer Protection is now looking into actions the video games company is taking to amend the situation around the troubled launch. The regulator has requested a report from the publisher explaining the reasons that led to the problems with the game. It also intends to find out how the company is working on patches and what it is doing to reimburse the dissatisfied customers.

Dominik Jędrzejko, attorney-at-law and partner at Kaszubiak Jędrzejko Adwokaci, believes that hotfixes and refunds might not adequately remedy the alleged unfair practices. In that case, the authority may impose a fine of up to 10 percent of the company’s revenue.

CD Projekt said it was prepared to take “vigorous action” to defend itself in court. As for Cyberpunk 2077 itself, it has lost almost 80% of its active players since launch a month ago when it hit a whopping 1 million concurrent players on Steam. This kind of decline, though, is actually quite normal for single-player titles.
