BLAMFORGE - Edit Weapon Stats and Player Values With Sliders

Get updated info here: https://github.com/ionicether/blamforge

This is still in beta, so you may run into issues. Please let me know if you do.

Description

Blamforge lets you change weapon and player values in Halo: Campaign Evolved with sliders.

You run it, a browser tab opens, you drag a slider and hit Install. It builds the mod and puts it in the game folder for you.

Seventeen weapons and Chief so far. Offsets check out but not every weapon has been tested yet.

Master Chief — shield recharge delay, shield recharge time, health recharge delay, health recharge time

Assault rifle — magazine, reserve, set dressing ammo, rate of fire, spread

SMG, magnum, needle rifle, battle rifle, spiker — magazine, reserve, set dressing ammo, rate of fire

Needler — magazine, reserve, set dressing ammo, rate of fire (it speeds up as you hold the trigger, so there's a starting rate and a held rate)

Shotgun, sniper rifle, rocket launcher, fuel rod cannon — magazine, reserve, set dressing ammo. No rate of fire, they're single shot (you'd think the magnum would be too, but if you hold the button down it keeps firing.

Plasma rifle, brute plasma rifle — battery per shot, heat per shot, rate of fire (starting and held)

Beam rifle — battery per shot, heat per shot

Plasma pistol — battery per shot, heat per shot, and the same two again for the charged shot

Sentinel beam — battery drain, heat per shot

Grenades — how many of each type you can carry

Installation instructions

See github readme for installation instructions

Main features

[]Sliders for 17 weapons (not all weapons have been tested) plus the Chief's shield and health recharge time.[/]

[]Builds and installs the mod for you, no manual file copying[/]

[]Each mod is its own folder, so removing one is deleting a folder[/]

[]Checks the values in your game files before writing anything, and refuses if they don't match what it expects[/]

[]Remembers what you last installed[/]

[]Says which entries have been tested in game and which haven't[/]

[]Warns you when a value will break something, like a magazine over 99 on the AR where the counter on the gun only has two digits

Requirements

Python 3. 8 or newer.

It also needs retoc, but it offers to download that for you on first run. Nothing else.

Built against game build 2026. 08. 11. 1121610. If a game update moves things around, it'll stop instead of writing to the wrong place.

Microsoft Store / Gamepass support is untested.

Special Thanks

• []trumank for retoc and repak. None of this works without them[/]

  []Chance255, whose Chief Shield and Health Recharge Overhaul is what helped me find where Chief recharge offsets came from. That saved me a lot of time[/]

  []blam-tags. I used it to validate the shield and vitality offsets I couldn't figure out, which is how I worked out why they weren't doing anything[/]

  More Robust Tools

  Blamforge is deliberately small. Sliders, a few numbers, done. If you want more, there are bigger tools that have no affiliation with Blamforge or myself:

  • []MJOLNIR Core is an open-source modding framework and community platform for HCE. Launcher, tag editor, free camera, dev console.[/]

    []Baboon is a GUI tag editor that opens this game's paks directly. Built on blam-tags.[/]
