BLAMFORGE - Halo Campaign Evolved

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.

Sixteen weapons (not all tested) and the Chief so far. Eight are confirmed working in game and the rest have verified offsets but haven't been played, which is noted in the interface so you know what you're dealing with.

Installation instructions

See github readme for installation instructions

Main features

[]Sliders for 16 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.

Shout outs

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.
