Mod lets GTA V NPCs use Mk II ammo effects properly

A small behavior fix with big firefight consequences

Nozomu-san’s new version 1.0 script changes a long-standing GTA V oddity: NPCs armed with Mk II weapons and Mk II ammunition no longer have to act like they are firing plain vanilla rounds. Instead of treating those specialty bullets as standard ammo, the mod simulates the proper Mk II effects in AI hands, which means enemy encounters can swing from mildly tougher to brutally dangerous depending on the loadout.

That matters because the difference is not cosmetic. A scripted gang ambush, police response, or roleplay showdown can feel flat when an NPC carrying Explosive or Incendiary ammo behaves no differently than one using basic rounds. This release closes that gap on both Legacy and Enhanced, giving mission builders and players a more believable combat model that matches what those ammo types are supposed to do.

What the mod actually changes in combat

The core idea is simple: if an NPC is assigned a Mk II weapon with a Mk II ammo type, the game should respect the special ammo behavior. The mod says it simulates every Mk II ammo effect for NPC use, and that includes Hollow Point, Armor Piercing, Explosive, Incendiary, Full Metal Jacket, and Tracer.

Each one alters a fight in a different way:

• Hollow Point doubles damage to health, but not armor, so it punishes lightly protected targets fast.

• Armor Piercing changes how damage interacts with armor, making armored opponents less reliable as a safety net.

• Explosive turns impact shots into detonations, which can rapidly escalate any firefight into chaos.

• Incendiary can set pedestrians on fire, adding direct crowd-control pressure and a much more dangerous close-range threat.

• Full Metal Jacket boosts vehicle damage and penetration, making cars and cover less effective.

• Tracer reduces the standard tracer behavior, changing how visible the shots are during combat.

Taken together, those effects do more than add flavor. They force you to treat NPC weapon choice as a real combat variable, not just an inventory detail. A hostile with Hollow Point rounds becomes a sharper threat to health bars, while one carrying Full Metal Jacket can punish vehicle-heavy tactics and bad cover usage.

Why this matters for Legacy and Enhanced

This release is built around compatibility, which is exactly why it stands out. The listing says it supports both Script Hook V .NET Enhanced and the original Script Hook V .NET release, so the mod is aimed at players and creators across the current GTA V modding split rather than being locked to one branch.

The required native libraries are equally specific. For GTA V Legacy, the mod needs Alloc8orStandardNatives. For GTA V Enhanced, it needs Alloc8orStandardNativesEnhanced. On top of that, it requires Script Hook V, the library that lets custom .asi plugins access GTA V script native functions. AB Software Development notes that Script Hook V does not work in GTA Online and will close GTA V if the player enters multiplayer, so this is firmly a single-player and modded-session tool.

That single-player limitation is not a footnote. It is the main boundary that determines where the mod belongs. If you are running story-mode combat overhauls, police scenarios, or scripted encounters, this is the kind of behavior fix that can make AI feel less like placeholders and more like real opponents. If you are anywhere near GTA Online, the compatibility line is clear: do not take it there.

Install path and version support

The install instructions are straightforward: paste the files into Grand Theft Auto V (Enhanced)/scripts. That keeps the setup familiar for anyone already using script-based GTA mods, and it matches the mod’s focus on modern Enhanced support.

The versioning also tells you where the project stands right now. GTA5-Mods lists it as version 1.0, classifies it under Gameplay / Weapons / .Net, and credits Nozomu-san. The page also describes it as a fresh release, with the file published two days ago, first uploaded one day ago, and updated just three minutes before the crawl. That kind of rapid update cadence usually signals an actively maintained tool, even if it is still being shaped.

For practical use, the key takeaway is simple: match the correct native library to your branch, confirm Script Hook V .NET support, and keep the files in the right scripts folder. If you are mixing Legacy and Enhanced mod setups, this is one of those releases where the version match matters as much as the feature list.

Best use cases for the mod

This is not a broad overhaul for every kind of player. It is a precision tool for anyone who wants enemy loadouts to matter more. The strongest use cases are single-player combat tuning, police scenarios, mission scripting, and roleplay setups where NPC weapon assignments are part of the design.

It also has a clear appeal for modpack builders. If your pack tries to make firefights feel more believable, the ability to assign real Mk II ammo behavior to NPCs closes an obvious realism hole. An enemy with Armor Piercing should not behave like a basic bandit, and a vehicle-focused encounter should feel different when Full Metal Jacket is in play.

The real value here is parity. Player rules and NPC rules finally start lining up in a way that makes firefights more consistent across Legacy and Enhanced. That is the kind of small technical correction that can change a whole encounter, especially when the right ammo type turns a routine shootout into something memorable.
