Now the Pikachu monsters are coming for you - that's the idea behind a video aimed at drawing tourists to the Swiss city of Basel.
The video has had nearly 65m views on Facebook.
Basel Tourism teamed up with marketing agency Fadeout to present a "reverse" Pokemon Go.
Now people are the ones being hunted in a twist on the global gaming craze.
Targeting young people, Basel Tourism told the BBC the video was showing off the city's attractions, such as "the beautiful Old Town, the river Rhine and its bridges".
