- Fixed critical issue with Hack Blocker not allowing specific users to use commands - Fabric: Fixed issue with Fog of War not correctly hiding players - Fixed Hack Blocker detection radiusHack Blocker: Improvements
- The module has been improved to only run the detections one time, instead of showing multiple inventories to players.1.5.2-pluginAug 5, 2026 New Module: Fog of War
Added a new module called "Fog of War" (inspired by anticheat-methods by the same name), this module allows Sentry to completely block and hide other players from getting information and packets about other players when they are hidden behind a wall or at out of sight. This completely removes any way of players that could use Wallhacks/PlayerESP/X-Rays to see and track other players behind blocks. - This module requires Sentry Prime. - In the plugin version, requires PacketEvents to be installed. <iframe width="560" height="315" src="https://www.youtube-nocookie.com/embed/5h1NxsRzeR8" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen></iframe>Features
