When you choose to start a new campaign, you have the option to choose from one of four difficulties. As the difficulty gets harder, the more accurate and damaging enemy attacks will be; enemies still take the same number of bullets to kill, no matter the difficulty. They are as follows:
- Recruit
- Regular
- Hardened
- Veteran
Before each mission begins, you will have the option to customize your loadout. As you complete more missions and Challenges, you will get more weapons that you can use in the missions. You can also check your scores for each mission, as well as the Challenges you can complete.
| NOTE - All missions are written assuming you have the Access Kit Perk equipped. With this on, you will get access to some extra weapons and equipment during missions. |
