This trailer offers a first look at multiplayer support in Call of Duty: Black Ops III, the upcoming military shooter sequel. For those who like what they see, preordering the game will guarantee access to the multiplayer beta when it begins. Here's the accompanying explanation, which notes some of these features vary on Xbox 360 and PlayStation 4):

Call of Duty: Black Ops III expands the possibilities of Call of Duty Multiplayer. The new movement system allows players to fluidly chain movements together while playing in maps that have been designed from the ground-up to push strong head-to-head action. Choose to play as one of nine new Specialists, each with their own look, personality, abilities, and level progression system. Finally, equip up to five attachments and an optic while customizing nearly every aspect of your loadout with the new Gunsmith, then tap the power of the Weapon Paintshop to give your weapon a signature look.
