Half-Life 2: Lost Coast is a playable technology showcase that introduces High Dynamic Range lighting to the Source engine. It is included with Half-Life 2, purchased on Steam. Originally planned as a section of the Highway 17 chapter of Half-Life 2, Lost Coast follows Half-Life protagonist Gordon Freeman as he travels up a coastal cliff to destroy a Combine artillery launcher in a monastery, which is firing on a nearby town.
