For 30 euro, its a bit steep for such short game, but at the same time, its money well spent. The G-Man doesn't play as much of a part as in previous games, in fact, he really just plays a cameo, but he would just get in the way of this exhilarating game. These games open a whole new portal for the series AND gamers alike. The difficulty can be a bit mediocre, but can get difficult in dark rooms with zombies swarming from all sides. It augments the atmosphere with excellent special effects and sound and some of the games aspects have been tweaked. The game is pretty dark and it still keeps the Half-Life blood pumping through its veins. In about three hours, its done and the only thing to do then is to wait for episode 2, but, of course, it's a trilogy so when it's all put together, it'll make one big game. First off, the main thing you notice when playing this game is it's length.
