How to replay a mission?

After successfully completing a mission, you’ll receive a Gold, Silver, or Bronze medal depending on your overall performance. You can view the medal you got from a particular mission by accessing Progress > Story > Chapter option in the main menu. You also have the option to replay a mission from that menu. Here, you can also check the tasks you completed. Completing all tasks will give you a Gold rating.

When replaying a mission, the game will create a checkpoint to save your current progress and will load that checkpoint after completing the replayed mission so you won’t be able to keep the items, ammo, and money you acquired from the replayed mission.
