Like the original Half-Life, this sequel has cinematic presentation and a better-than-Hollywood plot written by a legit science fiction author. There are memorable, well-written characters, such as the beautiful scientist Alyx and your friend, Dog. We can't spoil it, but watch for him. Plus, there's a presence in this game; it inspires an ominous unease. Half-Life 2 has an artistic but militaristic feel, and there are some genuinely scary moments, especially if you have any sort of headcrab phobia.
