Steam suffered a serious blunder that led to information about the achievements of dozens of unannounced games appearing online. The data were detected by achievement-tracking services, including SteamDB and Exophase. The list included mysterious titles connected to Avengers, Dune, Sonic and Sea of Thieves. The list is considerably longer and also contains many titles whose existence had not previously been officially announced. Valve has not yet disclosed details about the cause of the problem.
Steam API bug opened access to private data
The issue was noticed when the sites Exophase and SteamDB began recording achievements tied to many unreleased games. Exophase owner Mike Bendel confirmed on the ResetEra forum that the situation appears to be an error on Valve's side. According to him, some games with achievements that should have been hidden became accessible via the Steam API for a time. This allowed the site's automated tracking systems to scan the data and add it to their databases. It was particularly interesting to see titles that did not yet have a publicly visible name; in such cases Exophase simply assigned them an AppID number. The leak was not limited to a few random apps but affected a very large group of projects still awaiting official revelation. However, the mere existence of achievements does not always mean a game is close to release. Developers can prepare such elements well in advance, before they decide to reveal the project officially. The list includes both titles already announced and ones players only learned about because of this incident. Among the known games were Persona 6, Kingdom Hearts IV, Gears of War: E-Day, Judas and Silent Hill: Townfall. Also appearing were Fate/Extra Record, Gundam Rogue Orbit and Stupid Never Dies, titles that have already been officially announced. The Steam API should not, however, expose such information before release, so the whole situation looks like a configuration or security error on Valve's part.
Avengers, Dune and Sonic among the most mysterious projects
The most interest was sparked by entries about games that have not yet been officially announced. The list includes unannounced Avengers, Dune, Sea of Thieves, Sonic and Stellaris projects. In the case of Avengers there was an additional unconfirmed suggestion that it could be a long-abandoned THQ project being revived. However, this information comes from a leaker and should be treated only as a rumour. The leak also points to an unannounced game tied to Balatro, Brawl Stars, Candy Crush and Slime Rancher. Players also found entries suggesting a new production in The Walking Dead universe and a project related to Shrek. The list also featured mysterious titles linked to Twin Peaks, Heroes of Newerth and Toem. Among the more concrete names were ACE COMBAT 8, Attack on Titan 3, DRAGON BALL XENOVERSE 3, Deus Ex Remaster and Minecraft Dungeons 2. There was also Persona 4 Revival, Professor Layton and the New World of Steam, Turok Origins and Tropico 7. An interesting case is Squadron 42, whose presence on Steam confirms that the single-player campaign associated with Star Citizen is also coming to that platform. The release of Squadron 42 was recently pushed back to the second quarter of 2027. Interestingly, GTA 6 did not appear on the leaked list, so the leak itself does not confirm rumours of an earlier PC release for Rockstar's game.
A Steam API error led to the exposure of achievements assigned to more than 50 unreleased games and projects. The biggest stir was caused by information about unannounced Avengers, Dune, Sonic, Sea of Thieves and Stellaris projects. The list also includes many previously known projects, including Persona 6, Kingdom Hearts IV, Gears of War: E-Day and Silent Hill: Townfall. So far it is unclear how long the data were available or whether Valve will take further action after this incident.
