**EDIT**
Seems everytime they update the game the experiences need a refresh so that's when the codes stop working
***EDIT***
If the code breaks please send me a PM either here or on xbox. Please do not spam me with invites or messages...
I created a Portal Experience. Go to Portal > Host > use RT to go to Experience code > enter the below code.
Code: AA6S42
Objective: Crouch 5 times and you get a win.
