Supercell cyberattack exposes employee videos, no player data
Supercell, the Finnish mobile game developer behind Clash of Clans, disclosed that an unauthorized party accessed a platform used for hosting company meetings and presentations. Multiple cyberattacks targeted the company last week, with one causing the incident. The company has taken the service offline, blocked further access, and is investigating with security experts. Supercell has filed a police report and notified regulators, including the EU Cyber Resilience Act authorities and the Data Protection Ombudsman. The exposed material may include videos of current and former employees, guests, and partners, potentially containing names, images, voices, and email addresses. Supercell warns of potential phishing and impersonation scams and urges caution. The investigation is ongoing, and that no player data was affected.
Supercell reflects on Clash Royale update mistakes
At Gamescom Dev, Supercell design lead James Back and community manager Emilia Russell reviewed three major Clash Royale updates and what the studio learned from them. They discussed removing the popular Season Shop in March 2025 (which broadened reward access but damaged player trust), adding a Level 16 progression and Hero cards in November 2025 (which split player sentiment and prompted process changes), and the launch of a successful C.H.A.O.S. Mode (introduced in March) that boosted engagement without pay-to-win concerns. Supercell emphasised the importance of involving community creators earlier, communicating changes clearly, and treating player feedback as actionable input to preserve trust and engagement.
Supercell to Shut Down Squad Busters on December 14
Supercell has confirmed that its mobile game Squad Busters will be shut down on December 14, 2026, less than three years after its global launch in May 2024. The game will be removed from the App Store and Google Play on December 1, 2026, but players who have installed it can continue playing until the servers permanently close on December 14, when all events and timers end. In-app purchases have been disabled since October 30, 2025, and the window to transfer the value of 2025 purchases to other Supercell games closed at the end of that year. This marks the first time Supercell has shut down a globally launched game. The company ended development after several reworks, citing an inability to find a clear path forward without another major overhaul. AppMagic estimates lifetime revenue of approximately $67.9 million from 58.6 million downloads, with the US accounting for 30% of spending. Supercell has ruled out offline play, private servers, or releasing the code. The Squad Busters team remains employed, with most members already supporting other teams.
