Half-Life 2: Lost Coast is an additional level for the 2004 first-person shooter game Half-Life 2. Developed by Valve, it was released on October 27, 2005, through the Steam content delivery service as a free download to owners of the Windows version of Half-Life 2. Players control the Half-Life protagonist Gordon Freeman as he travels up a coastal cliff to destroy a Combine weapon in a monastery.
Lost Coast is a technology demonstration showcasing the high-dynamic-range rendering implemented in the Source engine. It was designed with environments to emphasize these effects. Lost Coast was the first Valve game with a commentary mode, in which the developers explain elements of design as the player progresses through the level.
The Lost Coast level was created for Half-Life 2, but was removed from the game. It was originally going to be a level in "Highway 17" where Gordon ends up in a strange place meeting a Fisherman. As a result, it has several minor story details that were not included in Half-Life 2. It received a generally positive reception, and there was consensus among reviewers that the new features included in Lost Coast should be integrated into future games released by Valve.
