StarCraft II Editor

StarCraft II Editor is a free creation suite for custom maps and mods in StarCraft II, best suited to aspiring map designers and experienced mod makers. Its broad map-making toolkit and Arcade publishing path make it a focused choice for creators building within the StarCraft II ecosystem.

Overview

The editor covers a wide range of custom content, from tower defense maps and MOBAs to campaigns and competitive ladder maps. Campaigns can load from one map to another and be played through the StarCraft II Arcade, giving creators a route from connected scenarios to a published experience.

It is a specialized tool, not a general-purpose game editor: its purpose is to change StarCraft II maps, mods, and game assets. Creators targeting other games should choose a tool built for those games instead.

Key features

The Trigger and Data Editors provide separate ways to work with game behavior and assets. The Data Editor’s Easy Mode organizes data collections and shows selected fields in a customizable table, which can make structured editing more manageable. Trigger editing includes a GUI for working with data table instances.

Terrain tools include up to 15 cliff layers and support shallow- and deep-water pathing. That range gives map makers room to shape varied routes and elevation, while the editor’s visual-effects and asset tools extend beyond terrain alone. Script editing and mod packaging are supported, alongside .SC2Map, .SC2Layout, Galaxy script, and XML data formats.

A Verify Bank trigger function checks whether a bank’s signature is intact. That is a targeted integrity check rather than a broad security feature. Blizzard also describes how to publish maps and mods on Battle.net, and Arcade creators have a default server-storage allowance of 300 MB, a practical cap to keep in mind for content-heavy projects.

Pricing

StarCraft II Editor: free. The free plan includes the editor for creating StarCraft II maps and mods, with no separate paid tier or trial needed to access the listed creation tools. It suits hobbyists and mod makers who want to build for this game without a software purchase. The 300 MB default server storage allowance is the relevant publishing constraint.

Platforms

The editor supports Windows and macOS. A patch note addresses Test Document working properly in the Mac editor, useful reassurance for Mac-based creators working with that function.

Who it's for

Choose StarCraft II Editor if your goal is to create StarCraft II maps, mods, or multi-map campaigns and publish them through the Arcade. Its combination of terrain editing, triggers, data tools, and scripting serves both newcomers to map design and experienced mod makers. It is not the right fit when your project targets a different game or needs a general-purpose level editor.

Pros and cons

• Pros: Free access to map and mod creation; supports several distinct map genres and linked campaigns; combines terrain, trigger, data, script, and packaging tools.
• Cons: Its scope is tied to StarCraft II; Arcade creators have a default 300 MB server-storage allowance.

Verdict

StarCraft II Editor is the clear choice for creators making custom StarCraft II content: it costs nothing and brings terrain, data, trigger, and publishing tools into one focused workflow. Look elsewhere if you are building for another game or if the Arcade’s 300 MB default storage allowance is too restrictive.
