Probably an alternate region version or maybe an earlier release that got removed and the devs uploaded a newer build under a different AppID in its place.P.S. found a duplicate / clone of the game on the portal. "Mad day 2" and "Mad day 2: Shoot the aliens" Achievements are identical, but the list of players is different.
I got the achievement "reach level 2" and "reach level 15". "Reach level 5" is missing. Out of 100,000+ players, no one got it. She's definitely broken.This game, getting to Level 5. Anyone of u, feel free to give it a test to see if its not just me. It should only take about 2 minutes.
