Half-Life 2: Lost Coast is an upcoming free add-on to the acclaimed first-person shooter.
As refreshingly optimised as Half-Life 2 was to run on low and mid range PCs, there's no doubt that a hugely significant chunk of its owners went out and upgraded their rigs with the specific intention of playing Valve's game without compromise, in all its staggeringly gorgeous glory.
But while many of us went out and upgraded to a gigabyte of RAM, stuck in a high-end Radeon or GeForce and spent a fortune, it's pretty clear that our PCs had plenty of headroom left - and now Valve wants to take advantage of that with the forthcoming release of a specially designed level called 'The Lost Coast'.
