Other tweaks that have taken place are Time to Kill (TTK) being tuned to be a little bit faster than the previous Black Ops game, various settings for your in-game HUD, a variety of audio improvements, and slide canceling. You can get a full breakdown on all the Multiplayer features here on the official Call of Duty Blog which also details features like Loadouts, Combat Specialties, and more.

Omnimovement, Gunsmith changes, Global Weapon Builds, Classic Prestige, and Mastery Camos will be some of the primary innovations you can look forward to across Multiplayer Zombies, and Warzone modes, but perhaps none will be as game changing as Omnimovement.
The way it works is this: Omnimovement will let you chain combat maneuvers together, like sliding, sprinting, and diving, all with a full 360 degrees range of motion (the upcoming Closed Beta will be a great chance for you to try this in action). It’s basically giving you all the tools to be a full-blown action hero, like shooting while diving forward, sideways, or backwards. Or pulling off combat dives off the edge of a building, rotating yourself in mid-air to face an enemy, and opening fire — there’s going to be a lot of incredible ways for you engage opponents.
