Valve announced today it finally plans to release Half-Life 2: Lost Coast next week. Lost Coast is a free level for everyone who owns Half-Life 2, and serves as an HDR technology demo based in an unreleased section of the "Highway 17" chapter of Half-Life 2. After Lost Coast is released, Valve says it will be working on getting some new content for both Counter-Strike: Source and Day of Defeat: Source, along with an update to the SDK, out the door.
