Helldivers 2 was delisted by Sony, not Steam, Valve rep says
Steam representatives are informing some Helldivers 2 players that the game’s publisher, Sony, pulled it from sale in regions where PSN is not available, not Steam itself.
Earlier this month, Sony announced Helldivers 2 players on Steam would soon be required to link to a PSN account for safety and security. It said this was always going to be a requirement for players on PC, but due to issues at launch, linking was made optional for a period.
The news was immediately met with intense backlash, which resulted in an influx of negative reviews from Helldivers 2 players on Steam. Many asked for a refund as Helldivers 2 was pulled from sale in 177 countries where PSN is not available, eventually leading to Sony overturning plans to enforce mandatory PSN linking for Helldivers 2 players on Steam altogether.
