Half-Life 2: Lost Coast is now available through Steam for all owners of Half-Life 2, Valve's announced.

Described as "a single-player level custom-created to showcase High-Dynamic Range lighting (HDR) in the Source engine", Lost Coast is, well, that - the coastal section of Half-Life 2 redone using special techniques that prettify it beyond all description.

Well, not all description - just beyond the bounds of our meagre technical understanding. Our technical wizard pals at Bit-tech understand it all a lot better and explain the difference in meticulous detail.

"As a technology showcase, Half-Life 2: Lost Coast's system requirements are very high," Valve adds. "During installation, Steam will prompt you if your system does not meet the recommended configuration. We hope you enjoy it." If it doesn't melt anything.

Sometimes we include links to online retail stores. If you click on one and make a purchase we may receive a small commission. For more information, go here.
