False alarm! Everybody continue about your normal business. This is not some official Half-Life 2 update; this is Half-Life 2: Update. The mod is a community-made attempt to give Half-Life 2 a graphical rub-down—enhancing its ageing visuals with some fancy technical trickery.

What, specifically, does the mod do? Here's the feature list:

Complete lighting overhaul including enhanced lighting, more detailed world shadows, and full High Dynamic Range Lighting (HDR).
New particle effects and improved fog.
Countless bug fixes, correcting both visual and game-based issues.
An extensive Community Commentary Mode featuring the voices of well-known Youtubers, including Caddicarus, Brutalmoose, Ricepirate, Balrog the Master, ProJared, and Ross Scott from Freeman's Mind .
Retains the iconic Half-Life 2 visual style and gameplay.

Half-Life 2: Update is due out tomorrow. It's free, but downloaders will obviously need to own a copy of Half-Life 2.
