YIPPEE KI YAY Trophy in Not A Hero
YIPPEE KI YAY
FIND THE SECRET DOOR IN BREDRIN PARK
How to unlock YIPPEE KI YAYBredrin Park is the second section of the game, where Days 8 to 14 take place.
The secret door is located in Day 13 "War on Drugs". After moving up to the top of the second building, you will need to jump right through a window to the roof of a third building then jump back down to the left to re-enter it (in a small room with a power-up). Drop down one floor and kill the guy there, then drop down again to reveal a "Door you can't see" sign. Keep going left and eventually enter the door to unlock the trophy (you don't need to complete the bonus stage). If you prefer visual help, please see the video below.
