It can be so much better with PC.
Imagine if there were mods for this game.
Plus a PC can have more memory and can be much faster.

the xbox is built to be a gaming console, so you can get good gaming power for a good price
everyone will have equal graphical power, so the devs won't need to richard around with graphics settings and stuff
Figured it was zombies survival so
oh, that's sound logic
