This secondary leveling system might not gain you any additional skills, but it's still pretty important if you want to become a legend in Night City, you know, that thing V and Jackie are always talking about.

But Cyberpunk 2077 doesn’t exactly explain what Street Cred is, how best to gain it, and why you would want any in the first place. Have no fear, though: that’s why I’m here, after all.
