nVison 3D works perfectly in this the latest but hopefully not the last Half-life episode. What are Valve waiting for? We gamers have been waiting patiently for HL 3 to come out but as yet there has been little if not any indication other than Valve patenting half-life 3. If you have played all four Half-life games then you like the rest of us can barely wait a moment longer for the glorious day when we finally see HL3 on our game store shelves. Nuff said other than this is a must for all first person shooter players. Not only will it grip you to your seat but you WILL finish the game begging for more. So in closing 3D works perfectly and for me it rates a definite 10/10 which is quite hard for any game to achieve from this reviewer. Maybe Gordon isn't just asleep this time, maybe he is in a coma so our enigmatic G-man may greet us with something like - "Ahh you are finally alive Misssster Freeman, Get up, get up and smell the diamonds"
