There are nine missions in Call of Duty: Vanguard. Each of these missions must be completed in sequence, and the story is linear, which means there are no branching paths and no important story-altering decisions to make. Just jump in and have fun.
Call of Duty: Vanguard is a great Call of Duty entry with absolutely stellar ser pieces, fantastic visuals, and plenty of modes surrounding an excellently fun campaign. The only downsides are the muddied stories & not to mention what is happening in the company that published it.
