Unarmored Marcus – Complete the Campaign on any difficulty*
*Note: Some people have reported that completing the campaign did not give them Unarmored Marcus. I’m suspecting this is a glitch, because if this happens and you look at the screen that shows your unlocked characters, it will most likely show that you haven’t met the criteria yet. Some have reported that simply beating the last boss again gave them credit. If this happens to you, please let me know in the comments, especially what you did to fix it.
