What StarCraft II Editor is

StarCraft II Editor is a free tool for creating custom maps and mods for StarCraft II on Windows and macOS. Creators can build tower defense maps, MOBAs, campaigns, and competitive ladder maps; custom campaigns can move between maps and be played through the StarCraft II Arcade. The editor includes Trigger and Data Editors for manipulating game assets and creating visual effects. In the Data Editor's Easy Mode, collections are grouped and selected fields appear in a customizable table. The Galaxy Editor supports up to 15 cliff layers and terrain editing for shallow- and deep-water pathing. A graphical interface in the Trigger Editor lets creators work with data table instances. Supported formats include .SC2Map, .SC2Layout, Galaxy script, and XML data. Blizzard's guidance describes publishing creations on Battle.net. The editor also has a Verify Bank trigger function to check whether a bank signature is intact. The default server storage space for Arcade map creators is 300 MB.
