You can't deny its popularity, but Call of Duty multiplayer is not for everyone. Many people buy the games for the short and sweet single-player campaigns, and would rather challenge their skills in Spec Ops challenges than suffer through the verbal lashings and ultra-quick trigger fingers that define the average COD multiplayer match. Activision recognizes the apprehension to jump online, and hopes to offer more replay value for these gamers with Modern Warfare 3's revamped Spec Ops mode.

"There's such hardcore players out there in the online community and you hear all the stories about (youngsters) swearing and ruining the experience," Michael Condrey of Sledgehammer Games told the USA Today. "With Spec Ops, you can really get in there and hone your skills in a more confined environment. I think it's a little more of an easy entry. I don't have as much time as I did when I was 20 to be honing my twitch skills, but this certainly gives me a venue to experiment."

According to the USA Today, co-developers Infinity Ward and Sledgehammer Games are beefing up the Spec Ops mode with online matchmaking, leaderboards, and a separate progression system from multiplayer. The centerpiece of the renovation, however, is a new Horde-like Survival mode that takes place on the multiplayer maps.

As you would expect, players face off against unlimited waves of increasingly difficult enemies. The map USA Today played, called Dome, featured a "Cold War-era desert radar command bunker" and some creative new enemies like suicide bomber dogs that explode a few seconds after you put them down. When the waves become too much to suppress with your assault rifle, you can use in-game currency to purchase defensive enhancements like turrets.
