+
+TrueFastball is a Borderlands 2-style Fastball overhaul for Borderlands 3. It increases Fastball damage with a configurable multiplier and accelerates the tested throw animation, while deliberately leaving Borderlands 3's native Fastball projectile speed and trajectory unchanged.
+
+## Features
+
+- Applies only to equipped Fastball throws and the actual Fastball projectile delivery.
+- Default Fastball Damage Multiplier: 2.56.
+- Multiplies the already-computed runtime GrenadeDamage, preserving native level and Mayhem scaling.
+- Default Throw Animation RateScale: 2.0.
+- Restores temporary throw-animation changes when the owning grenade action ends.
+- Does not modify Fastball projectile speed, gravity, upward velocity, or trajectory.
+- Exposes both release settings through the in-game Mod Menu.
+- Validates manually edited or otherwise invalid saved settings before use.
+
+## Compatibility
+
+- Fastball damage modification is gated to the actual Fastball projectile delivery.
+- Borderlands 3 Fastball projectile speed and trajectory are intentionally unchanged.
