Probably one of the easiest achievements I've ever gotten!
To do this right you need to be in solo ops mode. To get this just walk up to the RV and select solo op. When you start up there will be three pots in front of you.
To do the achievement properly you need to use at least
one of them to plant and select an AI team mate to do the solo op with you. Pick any ones you want.
Bear in mind the more AI you select the harder the difficulty becomes.
From there it's simple. Press up
on the D-Pad and bam! You've swapped places with the AI! Press multiple times to swap between all the AI characters or back to your original character if you wish and carry on winning!
