While Modern Warfare 2 may depict the harsh reality of urban conflict, Activision chose the penthouse suite of one of London's swankiest hotels to give us a final hands-on with the game. While the irony may have been lost on the publisher, the demo at least gave us the chance to see a brand-new level from the single-player game, as well as play an objective-based co-op level from the Special Ops mode. During this time, developer Infinity Ward's Robert Bowling answered our questions about multiplayer progression, cinematic influences, and using the game's Special Edition night-vision goggles for nefarious means.

The single-player demo took place at the end of the game's first act. You're on the hunt for an arms dealer, and after finding some marked shell casings, you're led to the dealer's right-hand man in Rio de Janeiro. The level opens as you're tailing a van. The van stops, and the dealer's confidant murders everyone in it. He then opens fire on your van--killing the driver as you and Soap MacTavish jump out and start a chase. We watched as Bowling ran after the suspect and then took him down by shooting him in the leg, allowing you and MacTavish to take him in for questioning.

After a short break, you take the victim to a quiet location, where MacTavish and a member of his squadron start interrogating him--using electricity "convince" him to talk. While MacTavish extracts the information he requires, he gives you instructions on where to head to find the man in charge of the operation. You enter Rio's slum with the Christ the Redeemer statue overlooking it, and you encounter resistance from the arms dealer's militia. The problem is that the slum is also populated with civilians, and Bowling would periodically fire into the air to make them disperse.

The slum section was a classic Call of Duty set piece, with a seemingly endless supply of thugs to dispatch as you progress. The difference was in small details--your character will knock out an old clip using the new one when using certain weapons, and when you're injured, blood fills the screen more than it did before. This was a ferocious section filled with rocket-launcher fire and dog attacks, and it came to a head when MacTavish dived out of a window to catch the subject.
