For those kindred souls who felt betrayed when the credits scrolled at the end of Half-Life 2 ("but I only just started playing 73 hours ago!!"), this is going to be akin to the feeling one gets when opening a bleary refridgerator and finding that the pizza isn't over after all.
Pros:
- You get to play (almost) the entire game alongside Alyx. She's kinda hot. And kicks ass with a shotgun.
- Fighting in the dark (whenever your flashlight battery runs out). This is scary and pretty cool. Kinda Doom-esque.
- Nice progression of the City 17 storyline. As always, they've done an incredible job meshing story-arc and gameplay.
- No real novelties with respect to the gameplay, weapons or enemies. But for those of us who just wanted more, it's enough.
