I've just finished Half-Life 2 on hard. It's not particularly challenging. The Combine soldiers seem to throw more grenades and their weapons do a little more damage. That shotgun will take you down very quickly if you're not careful.
I was hoping for a different post-credits cutscene but it's the same one you get on the normal setting.
I've gone through this game three times now. I thought that after this time, I'd give it a rest but on reflection I think that I'm going to play through it again.
