| Hopefully this will explain a lot more of the Halflife world...
HL1 left the player at a twist ending, with no resolving of anything.
HL2 gave the player a mere glimpse into one of the most interesting types of worlds, a post-apocalyptic one(Or at least one taken over by non-humans... presumably), but never let the player delve into the world and understand it, it was a huge tease, and at the end it was a worse cliff hanger than the first.
