That is something I don’t encounter very often these days. It was fascinating having a complete experience in the same game world but from a different perspective. Now you’re fighting for your life just like Gordon Freeman and even manage to cross his path just for a moment – which I thought was incredible at the time. Then suddenly you’re getting shot down and next thing you know, you’re right in the heart of an alien invasion. I still remember the exciting moment of loading up Opposing Force and witnessing that wild opening with you flying in on an Osprey with your squad ready to clean up the mess those crazy Black Mesa scientists had kicked off.
