No revenue estimate for PSN — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $15.4M — a different platform, not this one.

Big Walk

Big Walk is a cooperative multiplayer adventure about teamwork and talking. Set out with your friends through a wide-open world full of challenges, puzzles, and discoveries. You’ll need to work together to find your way around, stay in contact using an assortment of tools and toys, and figure out new ways to communicate when you suddenly find yourself speechless. Adventuring aside, there’s plenty of time to just hang out. Sit and watch the sunset, or steal your friend’s binoculars and kick them into the ocean. Spending time with friends is the best part of a big walk. Features: Talking!
