Rise and shine. . .
Not that I wish to imply you have been sleeping on the job. No-one is more deserving of a rest, and all the effort in the world would have gone to waste until. . .
Well. . .
Let's just say your hour has come again.
The right man, wrong place can make all the difference in the world. . .
So wake up, Mr. Freeman. . .
Wake up, and smell the ashes."
Game on.

Perhaps one of the best games I've ever played, it's truely spectacular. So realistic that those who suffer from motion sickness have trouble playing it. :S The phyisics engine rocks, the graphics are really pretty (when they're turned up to full), especailly the awesome water effects, the facial animations on main characters and other NPCs are just plain amazing, and the gameplay is really great.

The only things I don't really like about HL2 is that the storyline should of gone a bit deeper then it did, and that airboat bit lasted a bit too long. And what was up with the ending? I want answers, damn you!
But overal it's a really great game that no PC gamer should be without.

EDIT: Oh yeah, about the multiplayer. . .
CS: Source is fun. Teambased deathmatch, team who wins the most rounds wins the game. Kinda fun, but for teambased multiplayer 3D shooter, I prefer Unreal Tournament 2004.
However, for the fans of ordinary death match, HL2: DM has just been released.

Everyone gets a gravity gun, and you can kill each other with flying toilets and explosive barrels!

YAY!

Although it's very laggy and they've removed the crowbar.

It needs a bit of work done to it, but HL: DM is there.
