Half-Life 2: Lost Coast

The level begins with Gordon Freeman walking past the decaying piers underneath the shadow of a large Byzantine-style church, which is set up on a large outcrop of rock overlooking the small town of St. Olga. An unnamed man (referred to in the commentary as "The Fisherman") recognizes Gordon and directs him to the church, where the Combine have a headcrab shell launcher set up. He opens a gate, allowing the player to proceed, and waits for Gordon's return.

As Gordon proceeds up the cliff to the church, he encounters heavy resistance from Combine soldiers. Gordon fights his way through and disables the launcher. This, however, triggers an alarm, and the Combine block Gordon's escape. After the soldiers are defeated, a Combine Hunter Chopper opens an alternate escape route, though Gordon must destroy the chopper to make use of it.

The destruction of the chopper reveals an elevator which lowers Gordon back to the pier. The Fisherman congratulates Gordon and invites him to a feast in St. Olga, but at that moment the screen begins to fade out. The Fisherman states that Gordon is "getting all fuzzy round the edges" as this takes place.

Purposes

Half-Life 2: Lost Coast was developed as a playable technology demo, intended to showcase the newly-added HDR lighting features of the Source engine that were first implemented into Day of Defeat: Source. These HDR features didn't make a Shader Model 3.0 graphics card a requisite, due to introducing the harder-to-implement but theoretically less precise INT16 HDR rendering path, which all SM2.x, 3.x, and 4.0 graphics cards support by nature. This also allows FSAA and HDR to be simultaneously enabled on all DirectX 9 or greater graphics cards, even ones that support SM2.0. Lost Coast also demonstrates in general what the Source engine can achieve when system requirements and detail levels are significantly increased over games designed to run on a broad base of computers, with high-resolution textures and models. Lost Coast features minor storyline details that were scrapped from Half-Life 2, such as a headcrab canister launcher.

Developer commentary

Aside from visual fidelity and HDR, Lost Coast also acted as a testbed for their commentary system where, when the option is enabled, additional items appear in the game world that can be interacted with to play an audio commentary, each piece ranging anywhere from ten seconds to a minute of commentary. Players will hear the developers talk about what the player is seeing, what is happening, why they chose to do what they did, what kind of challenges they faced, and so on. Commentary tracks are represented by floating speech bubbles known as commentary nodes. To listen to a commentary track, the player places their cross-hair over it, and presses the use key. Doing the same again will stop the commentary track. Commands can be run when a commentary track starts and stops; in Lost Coast, this is used to completely disable the AI while the track plays. However, in Half-Life 2: Episode One, running a commentary track renders the player invulnerable to in-game damage for the time being rather than disabling the AI, likely for the purpose of not drawing away from the game.

Valve plans to make commentary standard in all of their future titles, and, as stated above, has already added it to Half-Life 2: Episode One, Half-Life 2: Episode Two, Portal and Team Fortress 2.

Recommended system specifications

• Processor: Pentium 4 2.4GHz or AMD 2800+
• Memory: 1 GB RAM.
• Graphics Card: DirectX 9 native
• 335 MB disk space (with Half-Life 2 installed)

Lost Coast is a 98 MB compressed download from Steam.

Despite some claims to the contrary, Lost Coast runs on computers with specifications lower than that listed above, albeit without some of the key focal features such as HDR. If a non-HDR capable card is used, the developer commentary is changed slightly to reflect this, such as Gabe Newell describing the effects you would see if you had the appropriate graphics card. It should be noted that a computer with the minimum specifications to run Half Life 2 will not be able to run Lost Coast. Computers closer to the bottom end of the Lost Coast minimum requirements are known to crash mid-game.

Recent systems using, for example, an Intel Core 2 or later/similar processors will trigger false warnings that the CPU is not fast enough to run the game, possibly by a huge margin. This is due to these modern CPUs being clocked much slower than the Pentium 4s for which the specs were written; this can be ignored, since the actual processing power of these systems is generally sufficient.
