thanks but I don't intend to stay here .....
I just wanted everyone to know how to unlock everything

The thank-you still stands.

So I just started playing Black Mirror 3, and I was disappointed to see no info in this thread about its bonuses

Is it discussed in another thread?

Hi SirGraham,

The only GB thread is in Discussions, HERE

But it doesn't give very much information. Perhaps if you post to that thread you might get a response from members who've found out more since then.
