LEGO City Undercover devs reveal interesting details about hit LEGO game

Instead of outright letting players shoot enemies, which was "far too violent for what the LEGO Group would like their IP related to," the studio resorted to other alternatives. This eventually led to the creation of the grapple gun, which players could use in-game to tie enemies up.

In the same podcast, LEGO Group producer Darryl Kelley also shared how TT Fusion came up with interesting additional unlockable content wherein the citizens of LEGO City Undercover would become zombies.

Obviously, this never made it into the game. Kelley explains that while it was "hysterical and amazing to see", there were some legitimate concerns. For one, Kelley added that they were worried if it was going to scare children or going too far. However, he did praise TT Fusion for coming up with additional content that he described as "never short of fun".

According to Kelley, LEGO City Undercover "was one of the best performing titles" on the Nintendo Wii U.

As of December 31, 2019, the original Wii U version of LEGO City Undercover had sold 1.15 million copies worldwide. This is good enough for the 18th spot in the 20 best-selling titles ever on the Wii U. The game later got a prequel, Lego City Undercover: The Chase Begins, for the Nintendo 3DS in 2013 and was eventually ported over to the PlayStation 4, Xbox One, PC, and the Nintendo Switch in 2017, it received co-op gameplay and benefitted from faster loading times.
