Today Valve Software will be releasing a playable demo of Left 4 Dead on both PC and Xbox 360 platforms worldwide. All Xbox 360 users should be able to download the demo from the marketplace from 10 a.m. GMT ( 2 a.m. PST ). It makes a nice change that it will not only be America that are getting this offer, but instead a worldwide release.

The demo concludes on November 18, when Left 4 Dead will be made available at retail outlets across North America and later on for Europe and the UK.

Edit: Corrected the release time
