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.
That lightmapping. The specular on the magnum. Am I in heaven?
if i learn my self the tools of modding i would use light mapping like this, and use props and textures with those from ep2 and beta models with a victory feast in the end with freeman and alyx getting married.
