If you haven't got the full game yet, you will want to try this out.

A free demo of Half-Life 2 has been released. Featuring some of the amazing digital actors and physical gameplay that has made Half-Life 2 the leading contender for Game of the Year 2004, the demo takes players through some of the early levels of the game and later transports them to the area of the game known as Ravenholm. The demo is available at ATI.com and requires a Steam account to install.

By taking the suspense, challenge and visceral charge of the original Half-Life, and adding startling new realism and responsiveness, Half-Life® 2 opens the door to a world where the player's presence affects everything around him, from the physical environment to the behaviors even the emotions of both friends and enemies. The player again picks up the crowbar of research scientist Gordon Freeman, who finds himself on an alien-infested Earth being picked to the bone, its resources depleted, its populace dwindling. Freeman is thrust into the unenviable role of rescuing the world from the wrong he unleashed back at Black Mesa. And a lot of people he cares about are counting on him.
