This massive overhaul mod completely changes how weapons work and how AI responds to you in GTA 5.

There are a wide range of tweaks within this mod that make gun fights with AI more challenging and ultimately more rewarding.

The tweaks fall into different categories. Weapon tweaks include recoil adjustments, damage balancing, and realistic magazine counts. AI tweaks make it so the combat efficiency of the police and gang members is both more realistic and more challenging. Pedestrians won’t always call the cops when you start shooting, too.

Gameplay tweaks make it so stealth kills are less likely to get the attention of the police, NPCs have improved ragdoll physics, melee combat has been reworked, and pedestrians have more realistic health.
