An unexpected bonus to this delay is learning that a prequel to Lego City Undercover has been in the works for release exclusively on 3DS, and will arrive in stores on April 21, only a month after the Wii U version drops. I have confirmed with Nintendo that this new game titled Lego City Undercover: The Chase Begins will be a full-blown retail release and not a smaller download-only title.
Lego City Undercover: The Chase Begins stars Chase McCain, the same cop you will play as in Lego City Undercover. Only in this game Chase is a rookie with much to learn, whereas in Lego City Undercover he is a hardened crime fighter that knows how to get the job done.
Unfortunately there is no additional information available about Lego City Undercover: The Chase Begins at this time. However, I have a few new Lego City Undercover screens to share below that include pig launching out of a cannon. I'm not kidding.
