8. Half-Life 2: Lost Coast – October 2005

Yes, before you say it in the comments, Lost Coast is BARELY a game. I know. It’s just one level that was cut from Half-Life 2 but repurposed by Valve, later on, to show off HDR in Source. Here’s the thing, though. It looks really good and is a nice, condensed slice of what I love about the Half-Life 2 games. Some combat, some puzzle solving, some weird lore about eating alien leeches (gross), and a nice big finish. If you haven’t played Lost Coast and love Half-Life, stop reading this list and go grab it. It’s free if you own Half-Life 2 on Steam.
