China's Tencent Holdings is going after the cheaters and hackers that infest PlayerUnknown's Battlegrounds as it prepares to bring the world's top-selling game to its home turf. From a report: Ahead of its official debut this year, the biggest gaming company on the planet has enlisted Chinese police to root out the underground rings that make and sell cheat software. It's helped law enforcement agents uncover at least 30 cases and arrest 120 people suspected of designing programs that confer unfair advantages from X-Ray vision (see-through walls) to auto-targeting (uncannily accurate snipers). Those convicted in the past have done jail time. Tencent and game developer Bluehole have a lot riding on cleaning things up for China, which accounted for more than half the game's 27 million users, according to online tracker Steam Spy. It's also the biggest source of cheat software, undermining a Battle Royale-style phenom that shattered gaming records in 2017 and surpassed best-sellers like Grand Theft Auto V. The proliferation of shenanigans threatens to drive away first-time users vital to its longer-term growth.
