Balanced Ballistic Physics

What Is The Science Behind The 120–140 Pro Sweet Spot?

Free Fire aim uses two forces: body pull and drag speed. Body pull drags your crosshair to the chest. Drag speed lifts your shots to the head.

What is Free Fire Zero-Glue Sensitivity?

Free Fire Zero-Glue Sensitivity is a custom setup for mobile players. It tunes your game to the 120–140 pro sweet spot. It matches your screen size, refresh rate, and touch speed. This breaks chest aim lock right away. Your crosshairs rise freely to the head during every drag shot.

❌ Low Sensi (Under 110)
Severe Chest Glue

Aim assist pulls hard. Your crosshair sticks to body armor and cannot lift.

✅ Pro Sweet Spot (120–140)
Zero-Stick Headshot Lock

Extra speed breaks chest lock with a short thumb swipe. Your shots lock right onto enemy heads.

⚠️ High Sensi (Over 150)
Sky Over-Drag Jitter

Light thumb swipes send bullets over the head. You miss shots and waste ammo.
