If you’re still playing LEGO Tower and are a fan of the LEGO Hidden Side theme, their latest update may be for you. NimbleBit has pushed out the newest update which features content from Hidden Side including some new rooftop sets, businesses, characters, and a vehicle. The minifigures include Parker, Jack, and J.B. while the vehicle is the go-kart from the Shrimp Shack Attack (70422).
As always, the updates to LEGO Tower are free and you can also play the game without spending any money. If you want to add me, my Player ID is 123P.
