Tankers!
We remind you that the top reward from the free Silver is an XT Container, while the Gold Tier (requires a Battle Pass from the Shop) will reward you with the Ricochet Legacy Skin in its final stage.
By the way, if you think you might have a hard time getting to the end of the Challenge, you can always snatch a Stars Bundle from the Shop and give yourself a nice boost.
So, hang in there tanker, and don’t let those cool top tier rewards slip through your fingers!
