Most features of StarCraft® II remain the same regardless of which expansion you choose—Wings of Liberty, Heart of the Swarm, or Legacy of the Void.
However, ranked and unranked matchmaking will place you on the ladder of the expansion you’ve chosen, and you can only use the units and game balance features of that expansion.
How to Switch Expansions
If you have multiple expansion levels and you want to switch to a different level, follow these steps:
- Select Menu.
- Select Options.
- Select Gameplay.
- Select your preferred version of StarCraft II from the dropdown.
