Efficiency

Efficiency is a progression achievement in the Mindustry system tied to the Efficiency; it is listed as an achievement entry and serves to record player progression related to that turret. As an achievement-type entity, Efficiency is part of the game's progression tracking rather than a buildable item or unit, and it references the Efficiency in its canonical designation. No additional mechanical inputs, outputs, or crafting recipe data apply to this entry beyond its role as a progression milestone.
