Complete all challenges for 2 weeks
Complete all the challenges for two given weeks to unlock the second of the seven challenges. Once you've got your loading screen, head to western part of the map, north of Snobby Shores.

This time the loading screen shows four barely visible markers on the crumbling wall in the photo. The markings read A3, B3, A4, B4. These are actually coordinates and you'll be able to find the secret battle token at the intersection of these four quadrants. The location is north of Snobby Shores and south of Haunted Hills.
