when i download the app that i cant login by steam account,by steamwhat can i do?
Even when you logged in through Steam the first time, you would’ve been asked for a password and email address. You should use the same password. If you’ve forgotten it, use https://www.sostronk.com/account_recovery
What should i put in Alias on the app?my email address?
Both Alias and email will work (your alias is Rock from what I can see)
