How should you define S-tier in Once Human?
S-tier means the best expected value across a hundred hero fights on maps like PvE servers, King's Row, and Midtown — not the gun that looks strongest in a controlled offline range. Mid-range rifles win many of the fights that actually decide matches: forty to seventy meters through doorways, open lanes, and sightlines.
Shotguns still own tight interiors. Snipers still punish long lanes on King's Row and Midtown. Everything between those extremes is usually pulse rifle and hand cannon country, which is why a well-built mid-range primary stays relevant season after season when mods and ammo types are available.
Always re-check live values after patches on Once Human. The hierarchy logic stays useful even when numbers nudge.
