I only downloaded HL2 again to get that screenshot, but testament to just how good it is, I stayed and played for another 2 hours. The opening few chapters are especially engrossing, and set the mood perfectly. The characters are brilliant, and the atmosphere is kept consistently tense, with some battles being gut-wrenchingly difficult. From G-Man’s creepy opening monologue, through the much copied physics puzzles all the way to the action-packed climax, HL2 is quite simply the best game I have ever played. If you by some miracle haven’t played HL2, its dirt cheap – buy it and play it now.
