The gameplay constants are in war3mapMisc.txt but only these that were changed get included. If you want to see the standard values/all fields, look into War3Patch.mpq\Units\MiscData.txt, War3Patch.mpq\Units\MiscGame.txt and I do not know where the language version-dependent stuff is, probably somewhere in War3xLocal.mpq.
🔨 Hive's 3D Viewer has been updated! 🔨 It now supports MDX1100 which should fix a lot of issues when viewing HD models in our 3D Viewer. We encourage you to check it out for yourself and report any issues you find in the Site Discussion board.
