The developers prepared a lot of new content, which players are now exploring.
Terraria recently received the "final" 1.4.5 update with new content in the style of Dead Cells and Palworld, as well as various improvements.
Many players decided to return to the project to check out the new additions, and the online player count on Steam began to gradually increase. As a result, over the weekend Terraria's peak concurrent player count reached 224 thousand players.
The last time Terraria showed similar player numbers was in 2020, when update 1.4 was released. At that time, the all-time record of 489,886 players was set, and it still has not been broken.
