Marathon Univ Patcher

Marathon Universal Patcher 2.1 is Naoki Yokoyama's all-in-one tweak utility for Bungie's classic Mac shooters Marathon and Marathon 2: Durandal. Rather than shipping as a single fixed mod, it exposes a menu of optional patches that the player can pick and choose, then writes them into a copy of the game's application file.

What it does

The patcher applies a curated set of feature toggles and stat tweaks to the Marathon or Marathon 2 binary, from quality-of-life adjustments to changes that boost the player's starting loadout or capabilities, depending on which patches you enable.

Universal across both games

The same tool understands both the original Marathon and Marathon 2: Durandal application formats, so you don't need a separate utility per game — hence the "Universal" in the name.

Using it safely

Always patch a duplicate of the Marathon application, not your master copy. The author's bundled documentation walks through each option; reading the docs first is genuinely required, since some patches are not subtle.
