They are getting a chance to save themselves, since USA marines are coming in town and not falling back this time. But during the battle apogee something goes terribly wrong and local school - the most safe place in city - turns out to be a death trap.
Awesome intro, but it takes WAY too long! People would get impatient waiting to start playing. If all the players were killed on this level they wouldn't they have to go through the intro again?
We have already fixed length of intro. But anyway thanks for comment! Now the intro lasts 20 seconds in the campaign and 10 seconds in Versus mode.
