Game Files/JSON

Game data is stored in several large JSON files. The structure is described briefly here.

My tools for gathering information from the game files: https://github.com/bobmath/BattleNationsWikia

Text
User-visible text in several different languages is stored in files named BattleNations_*.json. When Z2 makes an incremental update to the game, they often put new text in Delta_*.json to reduce the size of the download.

Units
Statistics for combat units are stored in BattleUnits.json.

Buildings
Building information is in Compositions.json.
