How to unlock the The Party's Here achievement in Shrek Forever After - Definitive Guide
To unlock this achievement, fire up a second controller and press "Start" to have it enter the game. You can now put down the second controller and ignore it. Use your primary controller to start the first level and play through a few tutorials until you get to the one where you battle several groups of enemies. After the battle, the achievement will unlock.
This trophy requires two controllers, but not two players, since you can easily defeat all the enemies for a given battle by yourself. I recommend knocking this trophy out during the first battle in the Swamp level, since this is a particularly easy battle. When the battle starts, just press on the second controller to have the second player enter. When you complete the battle, the trophy will unlock and you can press to have the second player drop out.
