Infinity Ward will be releasing a PC demo for Call of Duty 4 on Thursday at around 5pm UK time.
It will premiere on Yahoo Games (boo! hiss!), although official site Charlie Oscar Delta should be updated with various download locations as they become available.
Unfortunately there is no word on the 360 or PS3 versions, although Activision expects to have an official statement on their whereabouts tomorrow.
Call of Duty 4: Modern Warfare is due out on 9th November in Europe.
