Blizzard's official StarCraft II Client API, providing protobuf protocol definitions and a reference C++ library for full external control of StarCraft II. It enables building scripted and machine-learning bots, replay analysis, and tool-assisted play against headless Linux, Windows, or Mac clients.

Use cases

• build a StarCraft II AI bot
• train reinforcement learning agents on StarCraft II
• analyze StarCraft II replays programmatically
• run headless StarCraft II for machine learning research
• control StarCraft II externally from C++ or Python
• create a scripted bot for SC2 bot ladders

When to choose

• you want the official, low-level protocol for controlling StarCraft II
• you are building a C++ bot or a custom language wrapper on top of the protocol
• you need headless Linux SC2 builds, maps, or replay packs for ML research

When to avoid

• you want a high-level Python RL environment - use DeepMind's PySC2 instead
• you want a ready-made bot architecture - consider CommandCenter
• you need to control games other than StarCraft II
