A while ago i did some nvidia offer from steam and got HL2 lost coast for free. I never played it until now. I beat the game in about 25 minutes of playing?? Why is it so short? I went on steam store and looked and its a $40 game and when I went to the page it's not a demo i have. The $40 page says "You already own Half-Life 2: Lost Coast PLAY NOW" Why is it very short? and $40?
