VG247: Infinity Ward's Rob Bowling's revealed to VG247 that Modern Warfare 2 was initially supposed to have full co-op in the its main Campaign, but was dropped as it "ruined the experience" the developer was aiming for.

The final game instead has Spec Ops mode – a dedicated, mission-based co-op section playable either online or locally in split-screen.

"We did it early on; that's what Spec Ops started out as, as co-op through story," said Bowling when asked why Campaign co-op didn't make the final game.
