Originally planned as a section of the Highway 17 chapter of Half-Life 2,
Lost Coast is a single-player level custom-created to showcase High-Dynamic
Range lighting (HDR) in the Source engine, and is available free to all
owners of HL2 through a download from their Steam application (over 300Mb).
HDR simulates how the eye reacts when moving from a dark area to a bright
one, or vice versa. Day Of Defeat Source also used the effect. It starts
with Gordon Freeman falling into the water on an unspecified shore, with a
small town on a mountaintop visible in the distance. The gameplay is quite
short as it can be completed in about 15 minutes. You're given an option
to enable special developer commentary when the level starts, and if you
turn it on, you'll see little orange chat bubbles spinning in varying
locations. Hitting the "Use" key on any of these bubbles starts an audio
track, where different Valve developers talk about the technology, game
design, characters, or other elements of the demo. As a technology showcase,
it's system requirements are very high so make sure your system is up to it. |
