- The 'snow level' takes place somewhere in Kazakhstan and is called 'Cliffhanger'.
- The level starts off with climbing a ridge which, from their description, sounds mostly scripted, though you do the climbing yourself by pressing the triggers.
- General MacTavish makes a return and is featured in this first level.
- Once you've climbed up the ridge, you will make a trek through the snow, while your sight is slightly blocked due to falling snow, so you'll have to make use of your weapons' heartbeat sensor.
- This level is described as an infiltration mission, where you have to use stealth to advance, comparable to Ghillies in the Mist from the first game.
- After a couple of stealth kills and the placement of several explosives, you get caught and are forced to trigger the explosions early. Now shit hits the fan and all hell breaks loose in true Call of Duty fare.
- During the huge firefight, with soldiers, helicopters and jets all over the place, you make your escape on the well known snowmobile, racing downhill while fighting off pursuers.
- The 'Brazil level' takes place in Favela, a shanty town in Rio de Janeiro.
- Level starts out with you sitting in a car when suddenly you get fired upon.
- You are forced to leave the vehicle, as your driver got shot and bullets are still flying all over the place.
- Your mission here is to chase down some guy while not killing him, so it's a capture mission.
- Loads of stuff happening in this level too: civilians screaming and running away, exploding cars, dead bodies everywhere, it's utter chaos.
- After shooting the target in the leg, the demo ends, which is because they haven't finished the level yet.
- Infinity Ward now uses texture streaming, which enables them to construct much bigger levels. They show this off by zooming out of the Favela level.
- The lighting is greatly improved, with much more subtle details everywhere.
- The entire level is described as having loads of detail, with lots of shacks everywhere and alleys going in every direction, as well as newspapers blowing in the wind.
- The developer hints to Favela being a multiplayer map as well.
- A third level takes place in the desert.
- You drive off to a cliff, which you will rapel down from.
- After this, you will enter a cave and fight underground.
- The scene in the cave strongly resembles the scene from the Iron Man movie where Tony Stark constructed his first suit, which is something the developer was shooting for intentionally.
- The cave consists of a seemingly endless amount of corridors, and numerous large rooms.
