Undertale has reached a new concurrent player record on Steam, 10 years after it was originally released.
Indie developerToby Fox‘s RPG was first released in September 2015 and has enjoyed widespread critical acclaim and commercial success, with total sales onSteamalone estimated to be anywhere from5 millionto13 milliondepending on various Steam trackers.
As part of Steam’s current Spring Sale, Foxhas dropped the game’s priceto $0.99 / £0.69, a discount that will end on March 20.
Presumably as a result of numerous players buying the game and playing it for the first time, Fox says the game has passed its all-time record of concurrent players on Steam.
On Saturday, Fox posted a screenshot on X, showing that 10,739 people were playing the game on Steam at the same time.
“Since going on sale on Steam for only $1, Undertale reached a new peak of concurrent players for the first time since 2015,” Fox wrote, adding: “It’s still on sale for a few more days.”
Since Fox’s post on X, the game’s concurrent record has been broken again, with SteamDB reporting that on Sunday the game hit a peak of 11,071 players.
The previous peak player count for the game was 10,473, a peak reached back in December 2015, just three months after the game’s release when its momentum was continuing to grow.
Since 2016, the game’s peak has never risen above 5,000, meaning the new record marks a sizeable leap on Steam and suggests numerous new players are discovering the game for the first time.
Undertale is also available onSwitch,PS4,Xbox OneandPlayStation Vita, and currently has aMetacriticscore of 92-93 depending on the format.
With its influences ranging fromNintendo‘s Mother games to Nihon Falcom’s Brandish series, Undertale is particularly popular in Japan, leading to the release ofa DLC costume in Super Smash Bros Ultimatewhich lets players dress their Mii fighter as Undertale character Sans.
Fox is currently working on chapters 3 and 4 ofDeltarune, his episodic follow-up to Undertale.
