I can't believe how many people didn't enjoy R2, great game IMO. I did miss having a narrator but I mean honestly if the reason you didn't like the game is because there isn't a narrator, well come on.
I like how the health worked and that's how most FPSs are now I don't see why it would be a problem with this game. I also liked how only two weapons could be held at once. How realistic is holding 4 or more guns, Half-Life anyone?
