Cyberpunk 2077 took the gaming world by storm when it released in early December. Now, at the start of January, it looks like its player count has fizzled out considerably, at least for PC players.

According to Githyp, the game initially featured a whopping 1 million concurrent users. Now, it's struggling to maintain around 225,000. While The Witcher 3: Wild Hunt saw a similar drop after releasing, that happened within three months. Cyberpunk 2077's fall has occurred at a much faster rate, less than a month since the game hit retail.
