As Advertised

As Advertised is a challenge in the Badass Crater of Badassitude, that requires players to find two red loot chests hidden behind billboards.

Locations
The first loot chest is in the small group of buildings southwest of the Arena, behind the "We Got This!" billboard. As you approach the Seraph Vendor, you will pass a tall ladder on your right; climb the ladder to reach the loot chest.

The second loot chest is outside of the map exit to The Beatdown, behind the Torgue Bike billboard above the Catch-a-Ride station. The ladder is behind the hanging banners. Climb the ladder and walk along the rafters to the right, then make your way along the girders to the loot chest.
