This application will verify that you own Half-Life 1.
Please note: Your Steam Community profile must be public. If your profile is not public, we cannot access the list of games you own.
You can return to the start and try again.
This process is completely secure and we won't have access to your Steam credentials at any point.
We do not access any private data and, with exception of your Half-Life ownership status and your Steam ID, we do not save your Steam account information anywhere. The Half-Life ownership status and your Steam ID will be saved in your ESF Forums account.
You are not able to change the Steam ID associated with your ESF Forums account.
