Valve are currently doing a fucking awesome 66% off all HL2 games. As I am disturbingly aware that lots of you seem to not own the hl series let alone have played such fabulous games, now is the perfect opportunity for you to buy the entire series for less than hl2 costs normally, or if you're so shallow looking at the old-skool hl2 graphics hurts you, you can buy the entire hl2 series for less than ep2 would normally cost you.
