The PC single player demo of Call of Duty 4: Modern Warfare has hit the web. The demo features one mission called “The Bog,” where you get to try out a variety of weapons, tank destruction, tank protection, night vision and some intense action and firefights.

If you haven’t downloaded it yet then here’s a few good locations to get it from: Gamershell, Filefront, Actiontrip, Fileshack, Worthplaying or Fileplanet. And while it downloads, check the system requirements again to make sure you don’t have to run out and get a new piece of hardware.
