Linux Packages

Map Packs

This is the previous version of the Ladder 2017 Season 3 Map Pack

Replay Packs

Installing Map and Replay Packs

All additional game data should be extracted within the installation directory.

The default installation directories are:

  • Windows: C:\Program Files (x86)\StarCraft II\
  • Mac: /Applications/StarCraft II/

On Linux, the installation directory is the folder you extracted the linux package into.

The folder structure is the same accross all platforms. However you may need to create some folders if they are missing.

Standard folder layout:

  • StarCraft II/
    • Maps/
    • Replays/
    • SC2Data/
    • Versions/

Map Packs

  • Extract the zip file directly into the "Maps" folder.
  • In the API, a map can be specified as either an absolute path or its relative path inside this "Maps" folder.

Replay Packs

  • Replace the "" and "Replays" folders with the ones in the zip file.
  • In the API, a replay must be specified as an absolute path.

Stable IDs

These define the action mappings from ability ids in the protobuf api to the internals of the game. They also define some general ids that combine multiple abilities that have a similar semantic meaning (eg various forms of burrow, cancel, lift/land, etc). The stableid.json is updated occasionally with the game, but can also be updated manually by downloading the stableid.json from here and placing it in the root of your StarCraft II directory.
