What reward comes with 'platinum warrior'?

Games Halo Infinite
1

I did all the challenges and unlocked what ever plat warrior is but I dont know what it is exactly.

What you get is the Stone Green rare armor coating. Check your customization screen if you have it unlocked :slight_smile:

I finished the challenge and didn’t receive the stone green coloring so I think there might be a glitch with receiving it.
