Call of Duty: Black Ops/Operation 40

To get things rolling, here's the introduction: Your Mason, tied to an electric chair, surrounded by TV showing broadcast numbers and photos and a microphone. That's the setup and the voice is pounding you hard to reveal where the enemy location is.

Night time raid
You start in the bar owned by Carlos. You'll also be accompanied by Frank Woods. Anyway, a few soldiers comes in. As a tutorial, you'll learn to shoot, change weapons and using the aiming sights. Stick to using the machine gun but if you want to use the grenade launchers, aim near the cars as it's ineffective with enemies and vehicles by shooting at it.

Continue on until you reach a blockade by the Cuban police. Sprint on the left side. Reverse then drive. You'll reach a cutscene which marks the end of the first part.

Castro soldiers throwdown
You start in the daytime with Carlos and Frank Woods. Go on the zip line and start taking down enemies at the outset. By the time you reach the first building you can walkthrough, this marks your stealth attack which is brief. Anyway, you're going to reach a large building with a long hallway, full of soldiers intent on attacking your team.

When you reach the double-doors, you have a first breach. Aim and shoot as it goes in slow motion with two soldiers. Follow the room to reach Castro and his girl? Aim for the head for a cinematic moment. The girl gets killed after she's about to shoot you. Go outside and wait for reinforcement to pass.

The ungrateful escape
Now pass the sugarfield and sprint all the way to the plane. Essentially it sounds like war at this point. You'll be using the machine gun on the plane so shoot the soldiers at first, then tackle AA guns. Unfortunately an army of trucks is blocking the plane route. So you go to the last AA guns. Use it to unblock the runway to end the mission.
