Half-Life 2: The Lost Coast

It's a free extra level to Half-Life 2! Which uses incredible new technology to improve the lighting in the game by about a billion percent!

Really, it looks lovely. Gorgeous, even. I always thought Half-Life 2's visuals looked a bit sterile and lifeless, especially in the outdoor scenes, but this adds the missing life.

Didn't like my PC much and eventually just crashed horribly, but I've not seen a better argument for upgrading in quite some time.

I really am off to bed now. Really.
