Knowing through Gordon Freeman

(picture by IGN.com)
I recall playing Half-Life 2 for the first time and wondering who these guys on the left were (I mean... they could very well be nice people, yah?). I approached one of them: nothing happened. Then I picked up a can and threw it at him and he started bashing me up (I ran for my half-life, of course).
And that was how I knew he was a 'baddie'.
