In a recent interview with VG247.com (linked above), it was revealed that the original build of Modern Warfare 2 had a co-op campaign mode.

Infinity Ward's Robert Bowling briefly commented about it along with detailing a “substitute” for the co-op mode, Spec Ops mode.

To quote from the interview: “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.

“But it really broke the cinematic experience, took the immersion out of it, out of the story and the pacing and everything we’d spent so long crafting.

It just ruined the experience we were aiming for, so we took it out, kept the single-player for that one player intact and polished it.”

awesome,,, loving the fact the created pretty much a new game in the spec ops mode,,,hopefully if im not bullshitting myself that is, cant fucking wait for this game

im going to start wanking now for it actually

some really disturbing thoughts of a robot rubbing one out, running thought my head right now

your a filthy fucker michael

its spending to much time talking to you!

But them saying this makes me think that they actually care about the game and not just the profit, as most game developers would have just put it in anyway as the probably had spent a lot of time and money developing the co-op mode.

I see what they mean, split screen can ruin gameplay, if they did the full game co-op online i'd enjoy it, but lets face it, most of us will put in the game, jump online and do that for 6 months and think i bet the story's good

I didn't start the single player story on cod4 for 6 months loool.
