Giana Sisters: Dream Runners

The way I got it to pop for me.

Start a custom game.
Add your main Profile.
Add your second account on a second controller.
Then use you your main controller to Add Random(Online) to the 2 remaining places and then hit next.

Then just start the match by hitting A on both controllers and running with your main account until you get a star. Once you get the starts and the win screen appears the achievement will pop.
