The Division 2 features a photo mode. This lets you take photos of your agent from any angle. Taking a picture of a group of 4 agents unlocks the For Posterity trophy or achievement.
To Use Photo Mode:
- Press Options-Button (PS4) / Menu-Button (Xbox One). Then hold Square-Button (PS4) / X-Button (Xbox One).
The above image shows what it looks like in the menu. If this button prompt is not available for you yet, keep playing. For me it glitched out at first and after restarting the game the button prompt suddenly appeared. If it’s not there for you try rebooting the game and progressing the story until you get the onscreen tutorial for photo mode.
When you’re in a full group of 4 agents be sure to snap a picture to earn the “For Prosperity” trophy or achievement.
