PlayerUnknown's Battlegrounds is ending support for Steam's Family Sharing feature as part of a multi-layered effort to combat cheaters.
PUBG Corp, the game's developer, announced this change in a blog post today. The reason being that the studio has "identified a number of vulnerabilities" that cheaters exploit within Steam's Family Sharing.
"Please understand that we are introducing this measure to fight abuse and ensure a fair environment," PUBG Corp wrote.
Steam Family Sharing is a feature most games support that offers the owner of a game the ability to let other accounts access their libraries, whether it be on the same PC or on a different one. Whitelisted accounts can download and play with no restrictions, but only when the original owner is not currently playing any game on Steam.
In the same blog post, PUBG Corp revealed that it's developing a new anti-cheat solution internally. This is the same system it's been trialling on test servers these past couple of weeks. It's also the one that's going to block Reshade and other programs.
Any application that "hooks into the game" will be blocked, but the developer is aware that not all of them are malicious. With that in mind, PUBG Corp promised to whitelist benign applications as it continues to work on the tech. However, any software that "behaves like a cheat" will be blocked by default.
This new anti-cheat solution is still work in progress, but the first version of it will hit live servers next week. This is part of a major push at PUBG Corp to curb the cheating epidemic in the game. As part of the same initiative, the studio has set up a dedicated team that'll only focus on combating cheat programs.
Finally, PUBG Corp also confirmed that tampering with game files in any way, including deleting or modifying files, may get you banned. This is important because some PUBG players have taken to deleting Miramar files to prevent the map from coming up.
