ModTek
What it is
ModTek is a free mod loader for HBS’s BattleTech PC game. It loads mods that follow the mod.json format when the game starts, and lets modders package changes without overwriting game files. It resolves mod dependencies and controls load order without requiring edits to VersionManifest.csv. The project says newer versions include DLC support that the BattleTech 1.7 built-in loader lacks. ModTek supports BattleTech installations from Steam and GOG on Windows, Linux, and macOS. Installation uses a ZIP extracted into the BattleTech installation folder. Version 3 and later use UnityDoorstop to load ModTek without modifying game files. The project documentation covers JSON and DLL mods, advanced JSON merging, manifest manipulation, and HarmonyX support. It is licensed under LGPL-2.1. The installation instructions warn that BattleTech should be installed outside Program Files because Windows UAC protection can interfere. Linux instructions describe an environment-variable fix and caution against an obsolete, insecure system-wide ASLR workaround.
