Make sure you are at a location that has the MadPea experience enabled, like the MadPea sim. Add the game HUD there. You can also add the MadPea experience to your home sim or parcel (if you have the ability) by clicking on your sim name at the top of your viewer. An ‘About Land’ box will appear.
Go to the ‘Experiences’ tab. In the Allowed Experiences box, click the Add button. When the Choose Experience box pops up, type in MadPea, and click Go.
You will see the MadPea experience listed. Make sure it is highlighted and click OK.
That’s it! You now have then MadPea experience enabled on your sim/parcel.
