Call of Duty: Modern Warfare 2 showed a lengthy gameplay trailer at Summer Game Fest yesterday. The developers have also been doing a few interviews with the press, and in a roundtable Q&A transcribed by GamesBeat, Infinity Ward revealed that the game won't feature extensive destruction in multiplayer modes.

Smith: No. We’re not doing destruction. We can’t really afford it on a large scale across the map. I’m the worst person to kill everybody’s fun, but I can’t lie to you. I really feel like the design language has to–we have special effects artists that really love Jersey barriers, which are these little concrete barriers, and you can chip and dish into them. But if I can shoot that concrete, I should be able to shoot into the foundation of a house and everything else. We’re doing as much as we can–it’s better to phrase it as damage. Showing damage, showing wear, showing what’s happened without actually popping out structural pieces.
