    How to play
    1. There is no build to download: get the code from the project's repository.
    2. Build it as its README says. What the build gives, a program to run or the original game rebuilt for an emulator, is written there too.
    3. The project's page says what it needs from your own copy of Halo 3, if anything.

From SubmitGame's list, read Oct 26, 2026, with releases, stars and licenses as each project's repository gives them. The steps are the same for every project of a kind: its own page has the details.

Under the hood: every project behind it, its license and code, how they connect, and who made them.

About

Halo 3 is a shooter game where players primarily experience gameplay from a first-person perspective. Much of the gameplay takes place on foot, but also includes segments focused on vehicular combat. The balance of weapons and objects in the game was adjusted to better adhere to the "Golden Triangle of Halo": these are weapons, grenades, and melee attacks, which are available to a player in most situations. Players may dual-wield some weapons, forgoing the use of grenades and melee attacks in favor of the combined firepower of two weapons. Many weapons available in previous installments of the series return with minor cosmetic and power alterations. Unlike previous installments, the player's secondary weapon is visible on their player model, holstered or slung across the player's back. Halo 3 introduces "support weapons", which are cumbersome two-handed weapons that slow the player, but offer greatly increased firepower in return. In addition to weapons, the game contains a new class of gear called equipment; these items have various effects, ranging from defensive screens to shield regeneration and flares. Only one piece of equipment can be carried at a time. The game's vehicular component has been expanded with new drivable and AI-only vehicles.
