Prior to each mission, you have the ability to customize your loadout that includes a Primary Weapon and Attachment, a Secondary Weapon and Attachment, a Lethal and Tactical Grenade, as well as a Perk. Some of these are exclusive to the Campaign, and they are either unlocked by completing specific missions or completing a certain number of Challenges during missions.
The following lists will indicate what will be available at the start of missions, as well as what is unlocked upon completing missions and the Challenges. Note that as you go through the Campaign the first time, you are limited to what you can use during the missions that take place in the past. Once you finish the Campaign, you will be able to use future weapons in the past.
