Steam owners can now download the public demo of Left 4 Dead, Valve’s upcoming zombie shooter. Xbox 360 owners can also get their zombie freak on via XBLA, as the demo has been released there as well. This of course comes a week after the release of the pre-order demo, available to those who had pre-ordered the game. As you can see, I feel that this demo is much better than most full games out there, so I strongly urge all zombie fans (and everyone else) to download the demo and try it out. Look forward to the Ripten review of the game in the near future!
