Common Questions
Will a Sins of a Solar Empire key work in my country?
Keys are sold for a region: Global keys work everywhere, EU keys in Europe and usually the UK, US keys in the Americas. Each offer shows the region the store sells it for, and offers for the region you browse from are listed first. The store's page has the final word on where a key activates.
What is the difference between a key, a Steam Gift and an account?
A key is a code you redeem on your own account. A Steam Gift is sent to your Steam account as a gift and usually has the same region lock. An account offer is a new account that already owns the game; you log in to it instead of your own.
How do I activate Sins of a Solar Empire?
Redeem the code on Steam. The store's page shows the exact steps; our redeeming guide covers every platform.
