Cooperative gameplay modes are certainly extremely popular these days as many people want to progress through a game with their friends or family, either sitting on the same couch or by using the Internet in order to play.

The Call of Duty series has really taken the experience to a whole new level with the most recent CoD: World at War, made by Treyarch, boasting a cooperative single player campaign and a special Nazi Zombie one, both of them supporting four-player cooperative gameplay.

But the next title in the franchise, created by Infinity Ward, Modern Warfare 2, won't be boasting four player support, as it seems that from the studio's tests, two-player support is the best one, because it avoids a mess of commands and confusion between the gamers involved in that campaign.

“We don’t do co-op in our story because we’re crafting a very specific experience and we don’t want to ruin that by cramming co-op into it,” said Robert Bowling, community manager at Infinity Ward. “We take the moments that work really well with co-op, we bring them out and we put them in Special Ops. Two-player seemed to be the magic number for co-op. That’s when it stayed really fun and intense without becoming a [mess] of things. We just found that two-player was the most fun.”

The two-player Special Ops mode will also feature a lot of interesting things, Bowling adds, “Story’s all about pacing. Sometimes moments get toned down because they don’t fit with the pacing of the experience you’re trying to deliver. There (in Special Ops) it’s all about fun. It’s about playing over and over again, getting a better time – you’ll have a time at the end of it – it’s about challenging a friend going in on co-op and trying to beat it on veteran.”

So, there you have it, co-op fans, in order to get things as simple as possible, Modern Warfare 2, one of the most expected titles of the end of the year, at least according to its publisher, Activision, will only feature a two-player cooperative mode.
