Timefall mod for Half-Life

My name is Jordan Freeman. My only family is my grandfather, Gordon, and he is old and sick. Today the old man got up early,and woke me too… from the bad dreams I always have. He took me up to the old closed area… people call it “Evil Black Mesa.” For me it is not so bad a place. There, I can be alone.There, the old man has taught me many things; how to handle weapons, rock-climbing, and other survival techniques. Today he tells me my training is complete and I must begin my first mission. I don't understand all his talk about a ‘first mission’ but I trust him and I listen carefully. He says I must climb up the black wall, nearly to the top. On the other side is a cave, climb down and find a way out and home. Good luck and be careful, he says, as he turns to walk back down to our little village.
