Team Player - Call of Duty: Modern Warfare 2
After selecting the difficulty you want to play the game on, the game places you in the heat of the action right away. Your goal is to dispatch the enemy soldiers in the distance, after which a few jeeps will appear on the upper left bridge. Take these out, then move over the bridge to continue. Hop into your Humvee and you'll automatically position yourself behind the chaingun.
The first part of the ride is uneventful, but during the second half you're required to take out the enemy soldiers on the rooftop. It doesn't take long until your vehicle is hit by an RPG rocket, so quickly take shelter in the nearby house.
Head upstairs, take out a handful of enemy troops and take cover by the windows. When you've got eyes on the school, enter and terminate the hostiles, including those in the hall up the second floor. Proceed to the far end of this hall, and kill several more soldiers in this room.
ENEMY INTEL #2:
This Intel can be found after proceeding through the hall with the enemy gunners shooting through the windows earlier. After passing through this hall, check out the classroom to your right/west at the far end. This is right after someone says: "I think I saw one go in that classroom". The intel is located in here.

After this, follow your teammates into the alley northwest and kill several more enemies here. Go down the left street at the intersection, dispatch a few enemies and meet up with General Shepherd at the checkpoint.
