McPixel 3

Round 2-A. After completing the first round and returning to hub world walk left until you come to an alley and go up it, follow the path up again and pay the creepy dude in the long coat 80 coins (you earn coins for completing levels in rounds). Climb up the ladder and board the helicopter. This will start round 2-A

Once you get to the third level of this round don't do anything. You'll be ran over by a bus almost immediately. Achievement unlocked.
