The video below shows off the new Call of Duty: Infinite Warfare multiplayer gameplay that is part of the game. There are all new weapons, score streaks, upgrades and many - MANY changes to Infinite Warfare multiplayer.
There are rigs instead of specialists. The rig you choose comes with specific tactical advantages and a special weapon. This may be even more important than the specialist choice in Call of Duty: Black Ops 3.
The multiplayer includes a new objective mode where you need to take control of a drone in Defender -- as well as the multiplayer modes that you know and love. There is another weekend of the Call of Duty: Infinite Warfare beta coming up so you can try it out.
There is a focus on rewarding multiple playstyles and elements from old school Call of Duty games.
In the multiplayer mode you will craft weapons. You collect scrap parts as you play and unlock them in Supply Drops. When you unlock a base weapon you will get access to build prototypes. These can include additional perks that give you an edge. There is even a tactical nuke.
