Lost Ark is already one of Steam's biggest-ever games, overtaking the likes of Apex Legends and Among Us in peak concurrent users, even before it goes free-to-play later this week.
Per SteamDB data, the game's peak concurrent users currently stand at 532,476, placing it sixth in Steam's all-time list behind only New World, Cyberpunk 2077, Dota 2, CS: GO, and PUBG. Incredibly, it hit that number within 4 hours of going on release as a paid game, even though it will become free-to-play on Friday.
That sheer influx seemed to be causing some problems initially, with users reporting connectivity issues and increased queue times that prompted developer Smilegate to open another North American server shortly after launch:
Lost Ark is an MMO / ARPG with isometric action similar to the Diablo games, featuring 15 playable classes, a cinematic story-led campaign, and co-op PvE combat. It was released in South Korea in 2019 and later in Japan and Russia, with a North American and European release finally arriving this week.
