Byster is a DayZ cheat with two aim modes, a gentle LegitAIM and a silent RageAIM, player and zombie ESP, loot by category and a live map of Chernarus.

Legit mode pulls the crosshair to the target with adjustable speed and smoothing, while Rage sends the bullet to the target without turning the crosshair. Each mode has its own radius, range and hitbox: head, neck, chest, pelvis or Humanizer. ESP shows a player's box, name, held weapon, skeleton, health and inventory, zombies show health and skeleton, and animals, cars and boats are labeled with name and distance. Loot is split into seventeen categories, from weapons, magazines and explosives to NBC suits, building materials, farming, traps and engine and body parts, and every item shows its quality.

The live map shows your position, heading and vehicles in real time, but only on Chernarus. Extras include a time of day changer, grass removal, battle mode, auto run and configs. It runs on Steam DayZ in windowed mode on Windows 10 or 11, builds 22H2–25H2, with no built-in spoofer. A day, week or 31-day key arrives once payment goes through.
