I would say something to explain it, but that’s silly. It’s simple: Kyle Baker, cartoonist extraordinaire, has created a game free to play called “Mass Murderer of Steel,” in which Superman and Zod destroy Metropolis in a fight, killing people and knocking over buildings in the process, basically like in “Man of Steel.”
Clearly, Baker was not a fan of that aspect of the movie, and many couldn’t blame him. For those who don’t care though, blow stuff up! I can say one thing though: this game stresses my computer out. Beware!
