Yes, this is real. Someone actually made a first-person shooter for the New Testament. From the game's Steam page:
"I am Jesus Christ" is a realistic simulator game inspired by stories from the New Testament of the Bible. Get into old times and follow the same path of Jesus Christ 2,000 years ago. Game is covering the period from Baptizing of Jesus Christ and to Resurrection. Have you ever wondered to be like Him – one of the most privileged and powerful people in the world?
Check if you can perform all famous miracles from the Bible like Jesus Christ. It is a simulation game and you can try to save the world as He did. Are you ready to fight with Satan in the desert, exorcising demons and curing sick people? Or calm the storm in the sea?
I have a lot of questions. Like, why is it possible to beat the game without dying? Can you change the outcome of Bible stories, or do you just have to recreate it step by step? Does that mean you get to kick the crap out of a bunch of greedy bankers in the game? Do you actually get to fight Satan, too? Like physically? Does that mean Jesus has attack skills? Are there power-ups to boost the abilities with which you've already been divinely bestowed? Why is Jesus taking Polaroid pictures of everyone he helps? Why isn't Jesus shaking his Polaroid pictures to help them develop before placing them in the Bible? If Jesus made his own picture-book diary as he went about his travels, then why did the Apostles have to write the Bible down 80 years later? And why is everyone white?!
