Before you buy a Steam account
Ask about offline mode, access restrictions or device compatibility before ordering.
Contact support- Can I play offline?
- Offline play depends on the game and the seller’s instructions. Some games require an internet connection or a separate launcher. Confirm compatibility before purchasing; shared access alone does not guarantee offline play.
