This is the most intriguing part of the phrase. Why emphasize that all achievements work? In many custom game modes, modded servers, or command-block-heavy contraptions, certain traps can inadvertently disable advancement tracking. A trap that relies on a custom damage type (e.g., “suffocation in a piston-extended block”) might not count toward a kill achievement. Worse, some “trap” designs in creative mode testing simply don’t translate to survival mode’s advancement system. By declaring “all achievements work,” the designer makes a solemn promise: this piston trap is survival-friendly, legitimately built, and fully integrated into the game’s progression framework. It is not a cheat. It is not a bypass. It is a tool for earning achievements, ironically, often by killing things that would otherwise kill you. You can build this trap in a pure survival world, farm hostile mobs for “Local Brewery” (by collecting their drops), or even trap other players for “The End?”—all without ever breaking the advancement system. In a community rife with hacked clients and exploit-ridden farms, the phrase is a badge of integrity.
