This is a brilliant idea that’s been around on YouTube for a while. The story starts, and at the end of the video you choose where the story goes by clicking a link to one of two videos based on the choice you’ve made. Just like the choose-your-own-adventure books from when we were kids.
This video looks to have been a promotion for a pizza shop. The story is silly but it’s a zombie pizza comedy in choose-your-own-adventure form so I shouldn’t be overly critical. Have fun, and good luck surviving to the end!
