Moving Out 2

Arcade levels are bonus levels that you need to unlock by collecting Arcade Carts, one of the three types of collectibles on this game. There are only seven Arcade Carts total, and you need to collect them all for an achievement, but you'll need at least five of them to be able to unlock this achievement. Refer to Getting the Gang Back Together (50G) for finding all seven Arcade Carts.

Once you've collect Arcade Carts, head to the arcade in Packmore (the building with the joystick icon above it), and there you can play the arcade levels. They are little challenge levels just like in the first game, which basically require you to take a heavy item through an obstacle course of some sort and get it to the truck at the end. There are typically checkpoints, and nothing is very difficult here (especially compared to some in the first game). Pick whichever five of the seven you want and complete them for this achievement.
