PUBG: Battlegrounds

A hundred players parachute onto an island, scavenge for weapons and gear, and fight inside a shrinking play zone until one squad is left.

PUBG uses BattlEye for kernel-mode anti-cheat.1 game in this family →, the game launched into Steam Early Access in March 2017 and reached full release that December. It moved to native PlayStation 5 and Xbox Series versions in 2020, with support for the older PS4 and Xbox One generations ending in late 2025.

BattlEyeAnti-cheatBattlEyeBattlEye is the kernel anti-cheat from BattlEye Innovations GmbH (Reutlingen, Germany), founded 2004. One of the longest-running kernel anti-cheats in PC gaming. The kernel driver (bedaisy.sys) and user-mode service (BEService.exe) are both catalogued in the Field Guide.5 games in this family → is required to play and starts with the game. If launches fail, repair the BattlEye install from the PUBG folder rather than disabling it. The kernel driver is only resident while TslGame.exe is running, so it is not active outside of a session. Krafton's weekly ban notices and the annual dev letter on pubg.com are the most current source for enforcement scope and policy changes.

PUBG uses BattlEye, a kernel-mode anti-cheat. The protected driver (bedaisy.sysDriverbedaisy.sysBattlEye kernel-mode minifilter driverOpen plate →, catalogued in the drivers section) is registered as a demand-start service: it loads when TslGame.exe launches and unloads when the game exits, so it is not running in the background between sessions. While the game is open, the driver sits at the kernel layer and watches process and thread creation, image loads, handle operations, and cross-process memory reads and writes on the game process. The user-mode pieces (BEService.exe and BEClient.exe) are also catalogued in the processes section. PUBG was one of the earliest mainstream titles to ship BattlEye in this configuration.

Krafton has a long, well-documented anti-cheat history on PUBG. The cheating problem on PC has been heavily covered since the 2017 launch, with BattlEye data at one point attributing roughly 99 percent of bans to accounts originating in China, a market that was also approximately half the player base. Krafton publishes weekly ban notices and an annual anti-cheat dev letter on the official PUBG news site. As of November 2025, the company reported about 7.81 million accounts permanently banned for cheat-program use, with weekly ban totals frequently in the tens of thousands. Readers can weigh that record themselves.
