When you start the game wait until the CYAN screen comes up and then click 5 times rapidly on the left mouse button and then 2 time quickly on the right mouse button. If you are playing with a controller hit L2 5 times rapidly and then 2 times with R2. It will take about 3 seconds for the code to work so be patient but once it does you can view either of the ending credits. Via the right way or the wrong way just decide which one by choosing it one your screen.
